I see:
A toy car
A toy car going down the wooden ramp
A wooden ramp
A ramp on books
Books
Measuring tape to measure the length of the ramp
A measuring tape to measure how far the toy car went
Ruler to measure the height of the books
Toy car travel a short distance from the ramp
Toy car travel a long distance from the ramp
The higher the height of the ramp the further the toy car goes
The lower the ramp the shorter the distance of the car

I saw the toy car above the ramp. When it was on the ramp, it had gravitational potential energy. The higher the ramp was, the more gravitational potential
energy it had. When the toy car was released, the gravitational potential energy was converted to kinetic energy. When the car stopped, the kinetic energy was converted to heat energy and sound energy. The higher the ramp was, more gravitational potential energy converted to kinetic energy when the car was released.

I see a car moving off the ramp
I see that when we put more PSLE guide books the ramp’s height increases
I see that when the ramp’s height increases the distance the car travels on the ground increases

Hong Zhe(42)

I see the car moving down the ramp
I see when we put our PSLE guide book higher,the distance of the car traveled is longer.
I see that when we put the PSLE guide on top of each other,it becomes higher.

1) I see that when the car is released from the ramp ,the car would be moving but when the ramp is placed higher , the car would be moving faster. 2)I see that when the car is moving down ,it would be faster.

I see...
- the toy car moving down the ramp after being released at the TOP of the ramp.
-the psle guidebook used at a “Wooden block”.
-the distance moved by the toy car from the end of the ramp.

Yutong (1)🤭

2019-01-31 06:38:17 UTC

-I see a car on the block
-I see blocks that have different heights
-I see the car moving down the ramp
-I see that the car moves further when the height of the block increases
-I see the car moves faster when the height of the block increases
-I see the car stopped moving after a it moved for a short dis

- A toy car
- Science PSLE guide book (used for wooden blocks)
- Wooden board
- Toy car moving faster as the height of the ramp increases

Fang Wen(32)

2019-01-31 06:39:56 UTC

I see a toy car moving down the ramp
I see that as we increase the height of the top end of the ramp, the toy car moves faster
I see that as the height of the top end if the ramp increases, the toy car travels further
I see that when I release the car from the same height, we have a slightly different result
I see that when I release the toy car, the toy car rolls in front
I see that the toy car eventually slows down and stops on the table
I see that when the toy car was at the highest point of the ramp, it possessed gravitational potential energy which was converted to kinetic energy when I released it and when it was moving and as there was kinetic energy, the toy car was able to move and when the height of the ramp increased, gravitational potential energy possessed by the toy car increased, and thus, more gravitational potential energy was converted to more kinetic energy of the moving car, allowing the toy car to move further.

Kieran(24)

2019-01-31 06:40:16 UTC

I saw the car gaining speed when it went down the ramp

I saw that as the ramp increased in height, the car increased in the distance traveled

I saw that the gravitational potential energy of the car above the ground convert into kinetic energy of the moving car

DANIEL(41)

2019-01-31 06:40:36 UTC

1.I see that when I let go of the toy car from a higher distance, it travels a further distance.
2.I see when we add more PSLE guidebooks to the ramp,the ramp would have a higher height,so there would be more gravitational potential energy stored in the car.

Isaac lim(14)

2019-01-31 06:40:45 UTC

I see:When we released the toy car,the toy car went down the ramp.The toy car had gravitational potential energy and kinetic energy.Once it reached the end,it reduce the speed slowly.The toy car had kinetic energy then and soon the toy car stopped

Justin (16)

2019-01-31 06:41:16 UTC

I see a boy preparing to go down a ramp with a skateboard🛹 .When he goes down the ramp,he moves quickly and I can hear the wind whistling as he goes down the ramp.After a while,skateboard stopped rolling
(Why?)

2019-01-31 06:41:16 UTC

Tobius (8)
I see:when you release a car from a low ramp , the distance between the back of the car and the ramp is shorter than when you release the car from a higher ramp

Keith (17) :D

2019-01-31 06:41:31 UTC

I noticed that the greater the height of the ramp, the more distance (d) Car 17 travelled. However, when the ramp gets to steep, the car travels less distance (or FLIPS).

Xarius🏀 (38)

2019-01-31 06:41:33 UTC

I see that when my group members and I put the car onto a ramp at it’s lowest height,it couldn’t move at all.But when we increased the height of the ramp,the car was able to move bit by bit,and finally,after we increased it to the highest height of the ramp,the car was able to move fast and far.

Amberlyn (28)

2019-01-31 06:42:06 UTC

I see:
-A car moving down the ramp
-The car moving faster and faster down the ramp
-The car stopping after a few centimeters on the table away from the ramp
-The car doesn’t move if the ramp is not slanted enough
-The higher the ramp, the faster the car moves
-The lower the ramp, the slower the car moves
-if the ramp is too slanted, the car would just fall onto the table

Chan Man Yuk (3) 🦊

2019-01-31 06:42:33 UTC

-i see that the car that has been placed on the ramp will slide down the ramp when we release the car.
-I also see that the car is placed on different height of the ramp.
-I see that the car will travel different distance on the floor depending on the height of the ramp that the car is placed on

Eyan11

2019-01-31 06:42:47 UTC

Gravitational potential energy of the car is converted into kinetic energy of the moving car and then is converted into sound and heat energy when its wheels rub against the floor.I think this is the energy conversion of our experiment.I also think that there is still gravitational potential energy when it is close to the ground but on the plank.Lastly,I think that the car will go further when there are more PSLE guide books as the car will have more gravitational potential energy and cause it to go further.

Uleon {5️⃣}👾💶💣

2019-01-31 06:43:08 UTC

I see the effects of the energy conversion during the experiment of the car going down the ramp. The car moved for some time before coming to a stop.

Lydia(27)🌈⭐️✨🎵

2019-01-31 06:44:32 UTC

I SEE:That when I let go of the car from the top of the ramp,the car moves a certain distance from the ramp.When I increased the height of the ramp and let go of the car from the ramp then,it moved even further than when the height of the ramp decreased

Geng Hak (37)🐉

2019-01-31 06:44:33 UTC

I see:
- A car moving down a ramp.
- That if the ramp is higher, the car moves further.
- That if the ramp is at the lowest point, the car will not move at all.

Xarius🏀(38)

2019-01-31 06:44:38 UTC

I think it is because when the ramp is at a higher height,there would be more gravitational potential energy,the gravitational potential energy is then converted to kinetic energy of the moving car.The kinetic energy of the moving car would then be converted into heat and sound energy of the wheels when rubbing on the ramp.

Miguel™️ (31)

2019-01-31 06:44:50 UTC

I think that the kinetic energy which converted to sound energy from the car converted to heat energy after the car stopped for a few seconds as there was no more sound that could be heard after the car stopped for a few seconds.
I also think that the car still has gravitational potential energy after it stopped. The reason why I think so is that if the toy car landed on the ground, it can still fall down if it falls down a hole. Thus, I think that even if the toy car is on the ground, it still has gravitational potential energy.
I also think that if the car only goes downwards instead of also moving forward, like when the car is dropped for a height, the gravitational potential energy is still converted to kinetic energy as I think that anything that moves in any direction has kinetic energy.

Zhanxiang(3️⃣5️⃣)🇨🇳

2019-01-31 06:45:15 UTC

I see the 🚙 car moves further and away from the end of the ramp when I releases the 🚗 at a higher ramp than when I releases the 🚘 at a shorter ramp.

Alson 33

2019-01-31 06:45:15 UTC

I think that gravitional potential energy of the car at the top of the ramp is changed to kinetic energy of the moving car.The kinetic energy is than changed to heat and sound energy as it is rubbing against the ramp. 2)I think that as the height of the ramp increases ,there would be more gravitional potential energy that would be changed to more kinetic energy of the moving car,causing it to move faster.

Braeden(2)

2019-01-31 06:45:39 UTC

I see a car barely moving after adding one book as support to the ramp but as I increase the number of books,the distance that the ramp goes is increased and manages to go above 50cm

Jolynn Koh (19) 🐨

2019-01-31 06:45:45 UTC

I SEE...
-the toy car at the top of the ramp
-Rui Ting released the toy car down onto the ramp
-the toy car travelled down the ramp
-after the toy car reached the ground, it travelled some distance on the ground
-when the height of the ramp increases, the distance the toy car travelled on the ground also increases

Isaac(14)

2019-01-31 06:45:45 UTC

I think:The toy car still has a small amount of gravitational potential energy even when it went past the end of the ramp.I also think that a matter can stored unlimited energy.

Stephanie (36)

2019-01-31 06:45:47 UTC

When the toy car is moving downwards the wooden board, gravitational potential energy of it decreases and the kinetic energy increases.

Kevin(18)

2019-01-31 06:45:53 UTC

I see the car released from the ramp. It gained speed as it moved down the ramp. After it came down from the ramp, it moved a bit more before coming to a stop. The higher the ramp, the more the car moved before coming to a stop. I also noticed that different cars stopped at a different position after coming down the ramp despite being released from the same point.

Eyan11

2019-01-31 06:45:59 UTC

I saw that the car will have more gravitational potential energy on TOP of the ramp that is converted into kinetic energy when it rolls down the ramp and converts into heat and sound energy as it rubs against the ground.

Jolynn Koh 🐨 da 19th

2019-01-31 06:46:01 UTC

I SEEEEEE......
-the toy car at the top of the ramp
-Rui Ting released the toy car down onto the ramp
-the toy car travelled down the ramp
-after the toy car reached the ground, it travelled some distance on the ground
-when the height of the ramp increases, the distance the toy car travelled on the ground also increases

Elianna (10) 🦜

2019-01-31 06:46:10 UTC

I See:
-That when I let go of the car on the ramp, the car travels down the ramp and travels some distance from the ramp.
-That when the height of the ramp increases, the car travels further away from the ramp

Tan Tze Hung(39)😊

sheldonhartonolim — 2019-01-31 06:46:17 UTC

I see:
That when the car is coming down the ramp,it moves but very slowly.
When the ramp is higher up the car moves a little faster than before.
The equipment for the experiment like PSLE guide books,the wooden ramp,the toy car,measuring tape and the ruler.
That the toy car only traveled a short distance from the ramp

I see that the distance the car 🚗travelled increases ,whenever I increase the height of the ramp🎢.

I see........
a toy car that is moving which contains kinetic potential energy🚙
a ramp that is made of wood
a substitute PSLE guidebook as a wooden block
The car rolling down the slope

🧬car on the slope contains gravitational potential energy ➡️car pushed down the ramp contains kinetic energy➡️stops near the ramp all converted to heat and sound energy

DANIEL(41)

2019-01-31 06:47:26 UTC

I think that there is more gravitational potential energy in the car as it goes a higher height,Then

Amberlyn (28)

2019-01-31 06:47:48 UTC

I think:
-That as the ramp gets more slanted, there is more gravitational potential energy, which would result in more kinetic energy, making the car travel further
-That when the ramp is not slanted enough, the car cannot move as there is not enough gravitational potential energy to be changed to kinetic energy, which results in the car not moving

Yutong😶(1)

2019-01-31 06:48:00 UTC

- I think that when the car is on the block,the car has gravitational potential energy.
-I think that the gravitational potential energy of the car on the block changed to kinetic energy of the moving car when the car is moving down the ramp.
-I think that when the height of the block increases,the car has more gravitational potential energy.
-I think that when the height of the block increases,more gravitational potential energy of the car on the ramp will change to more kinetic energy of the moving car.
-I think the kinetic energy of the moving car changes to heat and sound energy when the car stops moving

Lee Xin Yi (22)

2019-01-31 06:48:11 UTC

I see:
A car sliding down from the top of the ramp.After it reaches the bottom of the ramp,it still travels a distance before stopping completely.

Jolynn Koh 🐨 da 19th

2019-01-31 06:48:18 UTC

I think......
-the toy car at the top of the ramp has more gravitational potential energy than when the toy car is at the bottom of the ramp
-the toy car that Rui Ting released down the ramp has kinetic energy
-the toy car travels some distance on the ground because the toy car has more gravitational potential energy that is converted to kinetic energy that pushes the toy car when it reached the ground, and thus the toy car travelled some distance on the ground
-when the height of the ramp increases,the toy car will have more gravitational potential energy converted into kinetic energy of the moving toy car, and thus when there is more kinetic energy of the moving car, the toy car will travel a farther distance on the ground.

Pamela(6)

2019-01-31 06:48:28 UTC

*I see the car moving down the ramp at different speeds when we stacked up more “blocks “(guidebook) as when the blocks are stacked higher,there is more gravitational potential energy that can be converted to more kinetic energy that allows the car to move down the ramp at a faster speed

*i see that the car moves further when there were more “blocks”(guidebook)/the ramp is higher because as when the blocks are stacked higher,there is more gravitational potential energy that can be converted to more kinetic energy that allows the car to move down the ramp Further

*

Kieran(24)

2019-01-31 06:48:45 UTC

I think that the higher the ramp gets the more gravitational potential energy there is and the car will be able to travel a further distance with more speed and that the surface of the ramp affects the distance traveled

Pamela(6)

2019-01-31 06:48:56 UTC

Rui ting 7 🥞

2019-01-31 06:49:19 UTC

I think...
-the higher the wooden block is placed, the further the toy car will move.
-the amount of gravitational potential energy effects the distance of the car.

I see a toy car 🚙 sliding down the ramp (the height was made of PSLE guide books 📚).

Lok Yi (9)

2019-01-31 06:49:44 UTC

I see...
📌 A toy car placed at the highest point of the ramp
📌 When it is pushed down the ramp, it rolls down and then stops after some distance
📌 When the car was at the highest point of the ramp, it contained gravitational potential energy as it was above ground. After being pushed down, the gravitational potential energy in the car was converted to kinetic energy for the car to be able to move. After rolling for a while, there was less kinetic energy in the car that was later converted to heat energy when the car stopped and the car wheels rubbed against the floor

WanYing(25)

2019-01-31 06:50:07 UTC

I see that when the height of the ramp is increased,the toy car released from the top of the ramp goes down quicker than when the car was going down a shorter ramp.

I see that the higher the height of the ramp,the further the distance travelled by the toy car when the car moves on the table after going down the ramp.

I see that when the toy car is released from the same height multiple times,each distance between the end of the ramp and the back of the toy car when the toy car stopped moving on the table may be different than the previous distance between the end of the ramp and the back of the toy car when the toy car stops moving on the table.

Jet15

2019-01-31 06:50:16 UTC

I think:
The higher the height of the ramp the further the toy car goes.
The lower the height of the ramp the shorter the toy car goes.
If the toy car is at the highest point of the ramp there is more gravitational potential energy.
If the toy car is at the lowest point of the ramp there will be lesser gravitational potential energy.
If the toy car goes down a ramp that is at the highest point of the ramp there will be more kinetic energy.
If the toy car is at the lowest point of the ramp there will be lesser kinetic energy

2019-01-31 06:50:30 UTC

Tobius(8)
I think:the gravitational potential energy of the car when it is on the higher ramp is more than when it is on the lower ramp .the gravitational potential energy is converted to kinetic energy of the moving car which is converted to sound and heat energy as the car was rubbing against the wooden plank

Jie Ling (40)

tan_eliana — 2019-01-31 06:50:59 UTC

I see.....
~ a toy car that is moving
~ the toy car has kinetic energy when it’s rolling down the slope
~ a slope that is made of wood
~ the car rolling down the slope
~ a substitute PSLE guild book as a wooden block
~ the car has gravitational potential energy when it’s on the Wooden block
~ when the car was pushed down the slope, the gravitational potential energy decreases.

The car on the wooden block has gravitational potential
energy. When it was pushed down the slope, the gravitational
Potential energy is changed to kinetic energy of the moving car and the gravitational potential energy decrease. When it stops near the ramp, the gravitational potential energy and kinetic energy of the moving car is changed into sound and heat energy

Leonerd (23)

2019-01-31 06:51:18 UTC

I think that the reason why when the ramp’s height increases the distance travelled by the car increases is because when the ramp’s height increases the amount of potential energy increases and with more potential energy ,More potential energy is converted to more kinetic energy of the moving car when it is going down the ramp,thus the car will travel a longer distance.
I think that the car will stop after going a long amount of distance is because the kinetic energy will be converted to sound and heat energy of the car when it is moving on the ground and the car will stop when all the kinetic energy of the moving car is converted to sound and heat energy of the car moving on the ground

Geng Hak (37)🐉

2019-01-31 06:51:25 UTC

I think:
- That the car travelled the furthest distance on the highest ramp as the car has more gravitational potential energy that is converted into more kinetic energy.
- That the car travelled the shortest distance on the lowest ramp as the car has less gravitational potential energy that is converted into less kinetic energy.

Justin (16)

2019-01-31 06:51:36 UTC

I think when the boy is on the ramp,the skateboard 🛹 and the boy both contains gravitational potential energy.When the boy and the skateboard 🛹 goes down the ramp,the gravitational potential energy of the boy and skateboard 🛹 on the ramp will be changed to kinetic energy of the moving boy and skateboard 🛹 , sound energy of the whistling wind and the heat energy of the friction of the skateboard 🛹 wheels rolling on the ramp.When the skateboard stops rolling,it means that the skateboard contains no more kinetic energy of the moving skateboard.The kinetic energy of the moving skateboard will be changed to some other energy of something else.

Raeann.c (4)

2019-01-31 06:51:45 UTC

I see that when I released the car, it travels further when the height of the ramp increases. The car also increases speed when the ramp is higher. When the car is on the ground, the speed decreases and it stops.

Leonerd (23)

2019-01-31 06:52:17 UTC

I wonder if the toy car which u need to pull it backwards and let go and it will start moving, if those types of cars are powered by elastic potential energy of the toy car’s wheel which will be converted to the kinetic energy of the moving car .

LUCAS 🤯 what I see▶️3️⃣0️⃣◀️♍️

2019-01-31 06:52:40 UTC

I see 😶 a toy car 🚘 sliding down a ramp (wooden ramp)made of books(PSLE guidebooks)
When the car is released from the to of the ramp,it’s gravitational potential energy 🛫is converted into kinetic energy (the car moving down the ramp),and the kinetic energy in turn is converted into heat and sound energy and in the end the toy car will stop moving 🔚

Randall [34]

2019-01-31 06:53:22 UTC

-I see a toy car
-I see a ramp
-I see a “block” a.k.a PLSE Guidebook
-A toy car moving down the ramp
-I see a toy car move faster when the ramp height increases
-I can picture the energy conversion : (I put in short form 👌🏼) GPE(toy car on ramp)—>KE+Heat energy+Sound energy(toy car rolling on ramp)

Xiao Ying (21)

2019-01-31 06:53:34 UTC

I see:
- I saw the toy car moving smoothly down the ramp when we released it from the top of the ramp
- I saw that when we increased the height of the ramp, the car travelled a further distance
- I saw when the ramp was too steep, the car fell off the ramp

Tan Tze Hung(39)😊

sheldonhartonolim — 2019-01-31 06:53:48 UTC

I think:
That when the ramp is placed at a short height,the car has less gravitational potential energy and then when it moves down the ramp it has lesser kinetic energy.
That when the ramp is placed higher,the toy car has more gravitational potential energy and then when the car moves down the ramp,it will have more kinetic energy and thus travel a further distance

Lok Yi (9)

2019-01-31 06:54:11 UTC

I think...
That the car rolled to a further distance when the height of the ramp increased because there was more gravitational potential energy in the toy car so when the car was pushed down, more gravitational potential energy was converted to more kinetic energy for the toy car to move a further distance before it stopped.

ZX

2019-01-31 06:54:23 UTC

I think this is because when you releases the 🚗 at a higher ramp, the 🚙 will have more gravitational potential energy than the 🚘 released at a shorter ramp,thus when the 🚗 at the higher ramp is released,it will convert more of its gravitational potential energy to kinetic energy.Thus, when the 🚘 has more kinetic energy it will travel a further distance.

Pamela(6)

2019-01-31 06:54:27 UTC

when the blocks are stacked higher,there is more gravitational potential energy that can be converted to more kinetic energy that allows the car to move down the ramp to a further distance at a faster speed

Amberlyn (28)

2019-01-31 06:54:38 UTC

I wonder:
-Where the heat energy from the car traveling across the table goes or what the heat energy from the car traveling across the table becomes

Xuan yi 💩🐺

2019-01-31 06:55:08 UTC

I think 🤔:When the car 🚙 is at the top of the ramp,it has gravitational potential energy.When the car goes down the ramp ,the gravitational potential energy is converted to kinetic energy of the moving car 🚙.

2019-01-31 06:55:30 UTC

I wonder what else affects gravitational potential energy either than the height and mass.Is there anything that affects chemical potential energy.Is there GPE on the ground because there is objects underneath our feet like levels and talking about that the objects under our feet do they have GPE?

Keith (17) Once again ‘<-<

2019-01-31 06:55:43 UTC

I thought about it:

When the ramp is too high, the car will convert most of the kinetic energy (as it is falling V Down V) to sound energy (When is SMASHES against the ground) and heat energy (When is has friction against air molecules) resulting in less distance (d) so I recommend using a 45° angle for the ramp to get a greater result in distance (d)

Alson 33

2019-01-31 06:55:58 UTC

I wonder what would the energy of the car be changed into after?

Jie Ren

2019-01-31 06:56:10 UTC

I see that when I put my toy car slightly ( 6 cm ) above the ground on the ramp , the distance travelled by the toy car was shorter than the height of the ramp(3cm) . The second time , the height of the ramp was 9 cm , the distance the toy car travelled by the the car is more than the height of the the ramp (24cm). The third time, the height of the ramp was 44 cm , the distance the toy car travelled was 100cm . The fourth time, the height of the ramp is 53 cm , the distance the toy car travelled is 64 cm .
I counclued that the higher the height of the ramp, the greater the distance travelled by the toy car .

When the toy car is on the wooden block , there is more gravitational potential energy than the kinetic energy, when the toy car is on the middle of the ramp , there are equal amount of gravitational potential energy and kinetic energy . When the toy car is on the table , the amount of gravitational potential energy is lesser than the kinetic energy .

The gravitational potential energy of the toy car on the wooden block is converted to kinetic energy of the moving car . When the toy car is on the ground , the kinetic energy is then converted to heat and sound energy .

Justin(16)

2019-01-31 06:56:35 UTC

I wonder when the skateboard is on top of the ramp and when the skateboard is rolling,does it contain energy that we do not know of?

2019-01-31 06:56:43 UTC

I wonder if the longer the wooden board is, will the distance traveled by the toy car change

Elianna (10) 🦜

2019-01-31 06:57:31 UTC

I Think:
-That the toy car has some gravitational potential energy when the toy car is on the ramp
-That the amount of gravitational potential energy in the toy car on the ramp increases when the height of the ramp increases.
-The amount of kinetic energy in the toy car moving down the ramp increases as the height of the ramp increases
-The toy car moved further away from the ramp when the height of the ramp increased because there was more gravitational potential energy that converted to more kinetic energy that made the toy car move faster and further away from the ramp.

Braeden(2️⃣)

2019-01-31 06:57:45 UTC

I think that as increase the number of books,the gravitational potential energy increases and the gravitational potential energy is converted into kinetic energy and the car moves faster but stops as the kinetic energy is converted to heat and sound energy

Chan Man Yuk (3)🦊

2019-01-31 06:58:14 UTC

-I think that the car moves down the ramp when we released it is because the gravitational potential energy of the toy car on the ramp is changed to kinetic energy of the moving car. Thus, the toy car moves down the ramp.
-I think that when the car moves down a higher ramp, it will travel a longer distance when it slides down to the floor.
-I think that the reason why the height of the ramp is greater, the distance of the toy car travelling along the floor is longer as the gravitational potential energy of the toy car increases when the height of the ramp the toy car is placed on increases. Thus, more amount of gravitational potential energy is changed to more kinetic energy of the moving toy car, causing the toy car to be able to move for a longer distance as the toy car has more kinetic energy.

I think gravitational potential energy is present in the car when it is at the top of the ramp. It changed to kinetic energy when it went down the ramp. As it went down more kinetic energy was produced as it went faster. At the end of the ramp, it will come to a stop eventually as the kinetic energy from the car will be converted to heat and sound energy.

Kevin(18)

2019-01-31 06:59:41 UTC

I think that gravitational potential energy is converted into kinetic energy as the car moved down the ramp. The higher the car is placed above the ground, it will possess more gravitational potential energy which converts to more kinetic energy.
I think that when the car came down from the ramp, kinetic energy converts to heat and sound energy, causing the car to stop.
I think that the cars came to a stop at different positions as the surface areas might be different, so the cars might have slowed down at different positions.

I think that when the car was on the ramp and was stationary,it had gravitational potential energy.The gravitation potential was converted into kinetic energy when I let go of the car.The kinetic energy of the moving 🚘 was then converted into heat and sound energy when it rubbed against the ground.Therfore it stopped. The car that was put on a higher ramp moved a further distance from the ramp as ,when the car was on the higher ramp, it had more gravitational potential energy then the car that was on the shorter ramp.

I wonder:
1)Why when the ramp is elevated to a very high height,instead of the car rolling down,it would drop down?
2)I wonder after the heat and sound energy of the wheels of the car when rubbing on the ramp,what energy would it be converted to?

Pamela (6)

I wonder if when the car is heavier ,it would move at a faster speed or a further distance?
I wonder if the wooden ramp was soaked with water ,the car would move faster ?
I wonder if one wheel was taken off,will the car still move at the same speed?
I wonder if ms nilam sat in the car,will the car move faster or slower ?

WanYing (25)

2019-01-31 07:00:53 UTC

I think the car goes down the ramp quicker when the height of the ramp increased as the car on the ramp before it was released possessed more gravitational potential energy compared to when the car was on a shorter ramp.The gravitational potential energy of the car on the higher ramp was converted to more kinetic energy of the car going down the higher ramp compared to when the car goes down a shorter ramp(which possessed less kinetic energy).More kinetic energy will allow the car to go down the ramp faster.Thus,if the car is wanted to go down the ramp faster,the car should be placed on a higher ramp as there will be more gravitational potential energy of the toy car on the ramp that is converted to more kinetic energy of the toy car going down the ramp.

I think that the distance between the end of the ramp and the back of the car when the car stopped on the table will be different despite using the same car going the the same ramp at the same height as force may have been used to release the car down the slope the first time and force may not have been used to release the car down the slope the second time.

Lee Xin Yi (22)

2019-01-31 07:03:25 UTC

I think:
-the higher the ramp,the bigger amount of distance between the end of the ramp and the car ,has just which slide down the ramp.
-When the car is released,gravitational potential energy of the car on the ramp is changed to kinetic energy of the moving car. The kinetic energy of the moving caris changed to heat and sound energy.

Fang Wen(32)

2019-01-31 13:13:27 UTC

I think that there will be more gravitational potential energy when the height of the ramp increases
I think that when there is more gravitational potential energy of the toy car there will be more kinetic energy of the moving toy car when the toy car was released
I think that the toy car will will travel further when it is released from a greater height
I think that the kinetic energy of the moving toy car will be converted to sound and heat energy as it travels further , so the car will stop as all the kinetic energy is converted to heat and sound energy

Raeann.c

I think:
The higher the ramp, the car’s speed increased.
When the ramp is higher, the car possessed more gravitational energy.
Thus, as the car goes down the ramp, more gravitational energy is changed to more kinetic energy of the moving car before the car came to a stop.

I wonder if the car still has sound energy after it stops. It could have no more sound energy or there is still sound energy as the car wheels rub on the ground and there is very little sound energy.
I also wonder what would happen if the car moved in the opposite direction. If the car moved up the ramp instead of going down the ramp, would the energy conversion be the opposite of when the car went down the ramp. When the car was pushed up, the kinetic energy would still be converted to heat and sound energy.
Before the car went down the ramp, i wonder if there is heat energy from the car at the top of the ramp.

Xing Cheng (29)

I think that the car has energy when it moves.
I think the ramp gives the car energy.
I think the ramp gives the car more energy when it has more wooden blocks under it.

I think the car will go down the ramp faster, if the ramp is higher. There will be more GPE. When the car goes down the higher ramp the GPE will be converted to more KE. The KE possessed by the car is then converted to heat and sound energy when the car’s wheels rub against the surface/table.

I think that the car has kinetic energy when it moves.
I think the ramp gives the car energy.
I think the ramp gives the car more energy when it has more wooden blocks under it.

First, a wooden block is placed under the ramp (This make the ramp steeper). Then, a car is released from the top of the ramp (The car then possess kinetic energy). After the results of this part of the experiment written down, another wooden block is placed under the ramp, making it steeper. Then, the car is released again, (The car now possess more kinetic energy) and the car is allowed to stop, (The car converts its kinetic energy to heat and sound energy which is why it slows down and stops eventually) then, the results are recorded again. This process goes on until all the wooden blocks are used.

The amount of gravitational potential energy becomes lesser when the car goes down the ramp.

When the ramp is placed at a lower height,the toy car at the top of the ramp will have lesser gravitational potential energy,then the potential energy will be converted to less kinetic energy and thus the toy car moves a shorter distance away from the bottom of the ramp.

-the toy car at the top of the ramp has more gravitational potential energy than when the toy car is at the bottom of the ramp
-the toy car that Rui Ting released down the ramp has kinetic energy
-the toy car travels some distance on the ground because the toy car has gravitational potential energy that is converted to kinetic energy that pushes the toy car when it reached the ground, and thus the toy car travelled some distance on the ground
-when the height of the ramp increases,the toy car will have more gravitational potential energy converted into more kinetic energy of the moving toy car, and thus when there is more kinetic energy of the moving car, the toy car will travel a farther distance on the ground.

U Leon{5️⃣}💶💳💣💰

2019-02-07 06:37:56 UTC

I think gravitational potential energy is present in the article when the car is at the top of the ramp. The gravitational potential energy is converted to kinetic energy when the car went down the ramp. As the car went down the ramp more gravitational potential energy is converted to kinetic energy as the speed of the car increases. A5 the end of the ramp, the car will eventually come to a stop as the kinetic energy is converted to heat and sound energy.

Geng Hak (37)

2019-02-07 06:38:22 UTC

I think:
- That the car travelled the furthest distance on the highest ramp as the car on top of the ramp has more gravitational potential energy that is converted into more kinetic energy of the moving car.
- That the car travelled the shortest distance on the lowest ramp as the car on top of the ramp has less gravitational potential energy that is converted into more kinetic energy of the moving car.

Lok Yi(9)

2019-02-07 06:42:45 UTC

I think that the moving car rolled to a further distance when the height of the ramp increased because there was more gravitational potential energy in the toy car so when the toy car was pushed down, more gravitational potential energy was converted to more kinetic energy for the moving toy car to move a further distance before it stopped.

Randall {34}

I think the car will go down the ramp faster if the position of the ramp is higher. The car on the higher ramp possesses more GPE . The GPE of the car on the ramp will then be converted to more KE of the moving car. When the wheels of the car rubbed against the surface or table the KE will be converted to more heat and sound energy.

I also think that if the car went down a U-shaped ramp, when it went up again, there will be gravitational potential energy that will be converted to kinetic energy once it goes down. I also think that the car cannot move on the U-shaped ramp forever as all of the kinetic energy will soon be converted to heat and sound energy.

When there were more books,there was 💣MORE💣 gravitational potential energy of the car was then converted into 💣MORE💣 kinetic energy of the moving car and then converted into 💣MORE💣 heat and sound energy causing the car to be able to go further.🛵

2)I think that as the height of the ramp increases,there would be more gravitional potential energy that would be change to more kinetic energy , causing the car to move faster and further from the ramp.

I think that when the ramp is higher there is more gravitational potential energy which is converted to more kinetic energy of the moving car.Therefor, the car travelled a further distance.

I see the car moves further and away from the end of the ramp when I releases the car at a higher ramp than the car I released from a shorter ramp.

I also sees the car moves faster when I released the car at a higher ramp than when I released the car at a shorter ramp.

When the skateboard is at the top of the ramp,it will contain gravitational potential energy.When the skateboard🛹is rolling down the ramp,the gravitational potential energy of the skateboard🛹 on top of the ramp will change to kinetic energy of the moving skateboard🛹,heat energy of the friction of the skateboard🛹 wheels🧿against the floor and sound of the rolling skateboard🛹wheels🧿.When the skateboard🛹stops rolling,it means the skateboard🛹no longer contains kinetic energy!😮

📌I think that the toy car was able to move down the ramp as when the toy car was on the top of the ramp, it had gravitational potential energy and when we released the toy car, the gravitational potential energy of the toy car on the ramp converted to kinetic energy of the moving toy car on the ramp.

I think:
-the higher the ramp,the bigger amount of distance between the end of the ramp and the car ,has just which slide down the ramp as when the car is released.Because when more the gravitational potential energy of the car on the ramp is changed to more kinetic energy of the moving car ,the car will move further.
-The kinetic energy of the moving caris changed to heat and sound energy.
