What did you learn today? by Kevin Davis

I learned that drops and hills contain speed. It make the whole roller coaster go faster. That's why when we go down a hill, we have butterfly's in our belly. It's because when we go down a hill, it makes our belly's feel like it is going up but it is actually just what you feel. Roller coasters make you feel like you are falling down. There are some roller coasters that do actually fall down but they eventually catch you. That happens to me all the time. It mostly happens when I am going down. I love when it goes down a hill and catches speed. That's why I love roller coasters so much. When I first went on a roller coaster, I got really scared and I cried a little bit, but that was because I got scared when it went down. That was when it got some speed. It gets speed from the tracks. Roller coasters are my favorite thing to ride and do in Spring and Summer. It is because I get to go swimming and sty up late, but mostly go on rides with my family and friends. I think that I am going to go to ride roller coasters with Sari and Emma maybe during the Summer too. We will probably get food and win prizes to but mostly ride all of the rides if we can. The most thing that I learned about roller coasters today was not only how it goes faster on a hill or when It is going down but going on hills and going down on roller coasters with your family and your friends because I think it is much more funner.

I learned that the basics of all roller coasters is gravity. Gravity is the force of a object that attracts the object towards earth. When you are on a roller coaster gravity helps the roller coaster go down hill. This is all of the forces that makes all of the loops, the drops, the turn, and how it goes up hill and down hill. Negative G attracts the riders on the roller coaster from there seats. Positive G Pulls riders to their seats. Lateral G makes the roller coaster have more angle while people are riding the roller coaster. The last force is called "Isn't typical force" and that helps the riders stay in there seats during a loop without safety harnesses but they are required while you are on the roller coaster. With all of these forces together they create a safety roller coaster and a fun ride. When I went on my first roller coaster I was scared at first. I went on the seats and I was really nervous. When we started to move I found it to be fun but when we went up, and up It went back to nervous then the drop came and I screamed so loud. But I found it to be fun. That is why I love roller coasters so much because they are safe, cool, and fun to learn about!

I learned today how the track makes the roller coaster go fast How it goes upside down and how the track pushes the roller coaster . flat less track is ride that does not have track so the the ride can stay safe . When people are going on upside down they have some to hold the people and the roller coast to not fall down . They are using potential energy by going up the roller coast and use and it use kinetic energy by going down .

I learned that some of the rollercoasters have magnets underneath the rails and that makes the Little car thingy stay on and that when we like well.... 1st we feel scared and dont want to try 2. We feel a little bit more brave and go with a friend 3. We go by oursleves 4. We start like rollercoasters alot and we try it more often. Those are things that happens to us we gain more Experince. When it goes up we "we tend to go slower but thanks to gravity it pushes the cart to go way more faster makeing it more fun". its basically a cycle we get scared we go with a friend we try it by oursleves,on and on and on, we all have to face our fears some days

You think we dont want to someday we have to and MANY people are scared that the Rollercoaster might brake but for a person that not scared they know what might happen but nothing puts the in a bad mood when they have rollercoaster :D.

Energy we use

We use kentic energy when we go down and we store energy when we go up that bumpy up thingy.

rules you should know

Yo should that you have to be higher like for example "you must be this tall yo ride" thats rule number one 2. NEVER EAT BEFORE GOING ON A ROLLERCOASTER its bad and can cause you to barf on other people including the ones waitng in line.3. DONT BRING CHILDS WITH YOU it can turn out very bad 0-0. Rollercoasters such as Zombie,the bear ride, and other stuff if you try bulding a cool rollercoaster you will be proud of what you made. Onther thing is that you can practice makeing a rollercoaster like use all the matrails you can make it will be more fun because you can use your amgnation and make you rollercoaster from small,meduim,to big all the way to extra large ;0.

the chain pull the car then lets it go at the top then with the help of gravity the car is able to go faster

it could use magnets or gravity the end

I learned that roller coasters are like trains and also bikes. They are like bikes because they hive a chain that makes the parts move. Like how the chains on a bike make the wheels move. Once the car has gotten to the top of the hill than the chains disengage and gravity pulls the car down. Roller coasters are like trains because they carry people in seats that remind me of when you are on a train. I like roller coasters because they make me feel scared and nervous but when you go down a hill or go around a loopty loop it is really fun. Another method for a roller coaster to go up then down a hill is a launch. Launch's can result from an energized magnets the moving of hydraulic fluid or compressed air. Launches can repel trains in a short distance. While riding one can both feel an experience and forces acting upon them.

I learned that wearing a harness is recamended by federal and state law.

I learned that the roller coaster has chain and those chains hold the cart so when the car goes up the cart is stuck to the chain.And if there was no chain the cart will fall back.

What I learned was that there are many different ways why roller coasters are a great way to have fun like gravity and the potential energy and kinetic energy when you go down the hill, that is when you go extra fast. Another thing I learned is that the chain they use for roller coasters is like the one they use for bikes.

I learned that there is a chain on a roller coaster and the chain helps move the roller coaster but then when it goes at a top of the hill the chain lets go and then it goes down by using gravity instead of the chain. I learned that another way for a roller coaster to go is a launch. You can make a launch with energizing magnets and moving hydraulic fluids and with the escaping of compressed air.

I learned that gravity is what is behind all this fun. Including some engineering. Gravity is what make s the car keep moving, and helps slow down the pull before you drop and when you drop.<

I learned that roller coasters use change lifts and compressed air to make roller coasters go. The video also said that to stay safe seat belts/Harness are ordered by the state law.

Isaiah: I learned that a roller coaster has many different ways to move like gravity it play a par in the roller coaster going fast when the roller coaster go down and bicycle chains make it go up an all about the different forces of the roller coaster. and I also learned about an astronaut named Alexander Gerst and his trip back to earth was like a roller coaster.

gravity is a big thing in roller coaster because gives it a lot of and crompesed air

roller coasters are fun but never eat food before you you might barf

I loved reading all of your great ideas and reflections from the video and article! Remember to use academic vocabulary in your responses! ☺
