I did this project to learn about how roller coasters work. There are three laws of motion. They are 1.Inertia 2.Acceleration 3.Momentum I also learned how much effort is put into making roller coasters. 

There was four jobs. One for each person. there was a lawyer, phisisist, historian, and design engineer. I was the design engineer. My role was to design the roller coaster and what mateirial is used. This is my  failed coaster.

This is my sucsessful coaster.It sucseeded because it had just egnough energy to make it.

We named the roller coaster Shark Attack.
