Newton's Laws are very important when creating a roller coaster.  He was the first person to discover gravity. I think these laws are pretty much common sense.  We got in groups and by the end of the project we made a roller coaster on a stimulater.  We then did an oral presentation about our role and about our roller coaster too.  When we did the stimulater there many fails because of not having enough energy.  We got to understand that roller coasters when created isn't as easy  as you think.  I never knew how important physics were, and when I got on roller coasters I didn't know how safe they probably were. 

In class we had to be either a physicist, design engineer, historian, or lawyer. The physicist had research how many  hills we can have, how many loops we can have, and how much kinetic energy and potential energy we can have.  The physicist also had to see how velocity, inertia, and momentum played a role so that we wouldn't go crashing through the ending point. The design engineer had to see what materials could be used, how designs have changed, and how long it actually takes to design a roller coaster before building it. The historian had to research the highest roller coaster, the fastest roller coaster and had to make sure we didn't name our roller coaster a name that was already used.  The lawyer had to see whether there were different laws in each state about roller coaster safety, how many lawsuits are going on right now and maybe how many deaths there has been.  I was the physicist and learned a lot of interesting facts.

 We decided to name our roller coaster Demon Hills because it has many hills.  We made the loop look like a devil when we drew it and the cart look like fiery devil body.  It looked really cool.  My fail was because I didn't have enough energy to get through the loop.  My success had lots of energy stored up so it was able to get through all the hills and loops.  Here is a link to go to the stimulater if you would like, it is called JASON Mission Center: Coaster Creator

This is an example of my roller coaster fail. I think it didn't work because of the hill I  have before my loop and that is where it got stuck.

 This is an example of my roller coaster success.  I think it worked because I had a really big hill and that gave me enough energy to go to the whole thing and the little hill slowed my roller coaster down at the very end.
