We think that it demonstrated Newton’s first law because one car was at the front. The other hit the one at the bottom and made it move.
We started to add pennies so there’s more weight. It made the car move much slower.

The cart started to go much slower. There was more friction and the car started to slow down. The weight made it move farther. We also realized that the cars kinda (not too much) went back. That shows that it was heavy.

We didn’t use books so we used the box everything was in. We’re going to pretend that we used 2 boxes. It would be more at an angle which means more acceleration which means more speed. It would mean that  the cars will go farther.

I typed more than I should have

# data[].attributes.body
The carts speed increased each trial. The slowest condition was the cart pushed. (Third trial)  We think it went the slowest because we added force and it increased the amount of friction.

# data[].attributes.body
The trial with the books had more force pushed to the plastic cup.

The ruler was more steep and when the marble went down because of gravity it started accelerating because of how fast it was going because the ruler was steep so the cup pushed pretty far.

We think that the marble would push further because of the mass and heaviness of the marble. When we tested it out, we were correct because the marble was made of metal. Also I noticed that the metal marble was so heavy, it didn’t want to roll down the ruler and kept sliding off before it hit the cup.

# data[].attributes.body
Answer to question 1: The one with no sandpaper, and no mass.
Andrew to question 2: The one with the sandpaper and without the extra mass and the one that had the sandpaper and the extra mass tied with 23.
Answer to question 3: It went slower because the sandpaper has a rougher surface, so there was more friction and the car went slower.
Answer to question 4: The mass (pennies) on top of the car barely affected how fast the car went.

# data[].attributes.body
When we pulled back on the band, the cart accelerated.

The father your are from an object before you run into it, the farther it will get pushed forward.

When we added the pennies to the cart, it got slower because it was heavier.

# data[].attributes.body
Changing the momentum made it go faster due to a higher range of force.

What happened in trial 5 was that all of the marbles, including the marbles that we launched. We think that the reason that that happened is because we surrounded it and then hit the marbles towards the other marbles quickly the amount of force was much, much higher. Therefore sending all of the marbles off.

The net force for trial 5 was kinda all over the place. Marbles in I’m every witch way, and then back every witch way.

# data[].attributes.body
The one that traveled the farthest was no sandpaper with 10 pennies. I think we messed something up because the one with no pennies was 38in and the one with pennies was 39in. The one that went the shortest was 25in which was the sandpaper with no pennies. I think we messed something up here because the one with pennies and sandpaper was 28 in.

The sandpaper effected the car because it didn’t go as far as it did without the sandpaper. The texture is really rough made the car go a shorter distance. The texture on the sandpaper was really rough while the texture on the tile was more smooth, making the car travel farther.

We originally thought that the pennies would make it so the car would have a shorter distance. The pennies made the car go faster I guess. It made it go faster because it made it have more power which means it went farther.

I typed even more than last time. Still too much :D

# data[].attributes.body
The speed increased as we pulled the elastic band back farther. More force was added to the cart when we pulled back on the elastic band, so more acceleration was used. The cart slowed down when the pennies were added because more mass was being pushed by the elastic band. This tells us that the more mass that is added, the slower the cart will go.

# data[].attributes.body
The cart released 3.44 the second one went 60 inches. The one that went to slowest was when the cart was pushed.

# data[].attributes.body
Q1: trial one because it had a steep slope to accelerate on.
Q2: gravity is pushing the ball down the slope which is picking up speed and force.
Q3: it would go slower but pick up more force making the cup move farther.

# data[].attributes.body
When the first car hit the cart, it made the other cart move. The cart kept moving but the friction from the ground and the wheels stopped it from moving.

The motion of the cart changed when we put the pennies because the pennies gave weight and gave the cart more mass and it slowed down the cart.

We think that if ramp was on four books then it would be steeper and it would go further.

# data[].attributes.body
It did have an effect on the marbles. The five marbles that pushed the other five marbles did not move once they hit the marbles but the other ones did move.

# data[].attributes.body
For the first one, we just dropped the car into the ramp, and it started to accelerate. It went to 39in and took 2.76 secs to get there. It traveled 14.13 inches per second, which is pretty decent. The second one, we put down the sandpaper, it decreased the length, but the speed increased. The speed was 2.19 seconds, and the length was 33in. It traveled 15.06 inches per sec.  The last one, we pushed down the car. The speed and length increased by a lot. The speed was 2.54 secs and the length was 49in. The car traveled surprisingly 19.27 inches per sec.

The normal release one had the slowest speed, it only traveled 14.13 inches per second. The one where we pushed down the car went the fastest, which it traveled 19.27 inches per sec. The sandpaper traveled 15.06 inches per sec.

Not as long as activity 2 but beats activity 1 of length. I need to type less.

# data[].attributes.body
The third trial went furthest and the second was the shortest.

The sandpaper made the car go slower.

The more mass made it go further.

# data[].attributes.body
The metal ball was exerted onto the plastic cup.

Gravity pilled the balls down the ruler on the top.

If the balls were larger and heavier it would either break the cup or ruler.

# data[].attributes.body
Yes, the changing momentum in the marbles did change results for 1 and 2. This was because more force was used in trial 1 than in trial 2.

The mass from each side of marbles changed once the still marbles came in from the moving marbles.

Momentum is the movement of an object once force is applied.

# data[].attributes.body
1: It’s inertia because it kept moving but it stop because of friction.
2: When there were 5 Pennines it actually went more than when there were none but when there was 10 Pennines inside it stopped before it went to the 15 mark for inches.
3: I think that it would make it go further due to gravity giving it more acceleration and therefore more speed.

# data[].attributes.body
Launcher mark 1 0 pennies time 1.3 distance 15 speed 11.53
Launcher marker 2 0 pennies  time 1.11 distance 52 speed 46.84
Launcher marker 1 10 pennies time 0.89 distance speed 1.23
Launcher marker2 10 pennies time 1.40 distance 23 speed 16.42

# data[].attributes.body
The ruler was angled more on trial one, so the marble accelerated more. Gravity pulled the marble down from the ruler and into the cup. If the marble was heavier or larger, the marble would go down faster because more mass equals more speed. If the cup was larger or heavier, it wouldn’t move as much because the marble wouldn’t have as much impact on the weight it’s hitting.

# data[].attributes.body
Whenever the cars didn’t hit the other they where not in motion bu ones they hit each other they went into motion.

The car went slower because of the weight of the pennies.

The car would go faster because the ramp would be higher.

# data[].attributes.body
When we pulled it back on the band, the speed increases. It increased due to it being pulled back, it gave it more power and time to move. If it’s pulled back very little, it makes the cart go very slow.

Because it had more force behind it, it increased the speed of the cart. The fastest was when we had no pennies and went to the second mark. It went 29in. The one where we had no pennies and it went to the first mark went 8in. The speed was 27.88 inches per sec for the second mark and it went 14.81 inches per sec for the first mark.

When we put 10 pennies into the cart, the speed decreased by a lot. The  29in turned into 16in. That’s a big difference! That’s slow! Also the speed for the second mark went from 27.88 inches per sec all the way to 14.15 inches per sec.

This is shorter than normal lol this helps my hands

Q1: trial 3
Q2: trial 4
Q3: the sandpaper made made the cart travel less because it caused more friction.
Q4: the carts mass made it travel further.

# data[].attributes.body
The more of the push it knocked the marble farther. For trail 5 the force on both the marbles knocked into each other and made them both go crazy! And for net force it was crazy with the marbles because with the force.

# data[].attributes.body
It demonstrates that when the the cart gets pushed it move because it gets pushed.

When we added the pennies the car went faster.

We think the cart would go faster and farther because it has more of an angle.

# data[].attributes.body
Q.1: In which trial did the car travel the greatest distance. Number one did 34in.
Q.2: In which trial did the travel the least distance. Number 2 and 4 have 23in.
Q.3: Explain how the sand paper effected the cart. It slowed it down.
Q.4: How did the cars mass effect how far it was able to travel. The pennies made it go faster. If it was in the front.

# data[].attributes.body
Yes! It made more fall off of the ruler. Some even fell off the side due to how fast the marbles went (or maybe someone pushed too hard). More fell off due to the force of the marble pushing the other marbles and making more marbles roll.

The impact changed due to the force and mass of the three marbles. The two marbles were able to go faster because of the lower mass. That ended pushing back more marbles towards the side where the three marbles started off than where the two marbles.

The net force was crazy because the marvels started to fly all over the place. The marbles started to go off the ruler from the sides due to the force from the marbles that were hitting the other marbles.

Just saying I’ve lost my ability to talk and type lol

# data[].attributes.body
Answer to question 1: For the second trial, the cup moved more because the ball was heavier and had a stronger force.
Answer to question 2: The marbles that we used were both heavier than the cup, so the cup moved more because the ball was stronger and had a greater force.
Answer to question 3: The cup would probably move more because the ball is heavier and has a stronger force.

# data[].attributes.body
Q1:
It went different distances in the same amount of time due to the different conditions in the trials
Q2:
There all the same but inches per second the fastest was the third trial at 20.333333

# data[].attributes.body
The force of the first trial had more force. It had more force due to the angle. It accelerated more on the ramp than it did on the second trial. It hit the cup at a faster speed which means that it had more force than the scribe trail.

The role of gravity in this experiment went like this. When the marble went down the ruler, the more that the gravity wanted to pull the ball down. When it was more at an angle, it made the gravity want to pull down the ball even more, creating more acceleration. It increases the speed, making the force stronger, which made the ball hit the cup faster the first trial than the second trial.

Of the ball was heavier, it would go at the same speed, due to the angle being the exact same as usual. The thing that would be different would be the force. Since the ball is heavier, it creates more force behind it, making the force much stronger.

Bonus we decided to do: What if the ball was lighter?
If the ball was lighter, it would have the same speed because the angle, which is pretty similar to the third question. The thing that is different is that the ball would have less force. It would have less force due to the weight of the ball. It if was lighter, than it would do the exact opposite of the heavier one.

Wow my longest one by far! Why did I add an extra bonus I didn’t need to but ok.

# data[].attributes.body
In the first trial the car traveled the farthest.
In the second trial the car traveled the least distance.
The sand paper added more friction that made the car slow down. The car traveled less distance with more mass added.

# data[].attributes.body
Question 1: It shows how different amounts of mass can affect how far a certain objects moves.
Question 2: It’s harder for the object of move because it has more mass each time.
Question 3: The car has more momentum, and more speed. It would hit the car harder and probably push it a little faster.

# data[].attributes.body
Q1: Went further but went out f control faster
Q2: The elastic had more force that transferred into the cart
Q3: On trial three it went less with mass but the same on trial 4

# data[].attributes.body
No for some reason it didn’t change anything.

Three marbles fell off the rulers
We think it had too many marbles at a time to push all of them off.

Three marbles fell off when we pushed five marbles into five marbles.

# data[].attributes.body
When we used sandpaper it went slower but when we pushed it it went quicker than the rest because you added more force to the cart when pushing it off the ramp.

Trial one had the least amount of speed out of the rest of the trials we tried out.

# data[].attributes.body
It took less time each time it went because the first one was 2.8m the second one was 1.85 and the last one was 1.81.

The first one because we didn’t push it that hard.
