In this project we designed and built roller coasters. With this project we studied to physics behind a roller coaster. An example would be how mass, friction, weight, speed, and velocity all apply to a roller coaster. I worked with a partner on this project and we named it TWISTER! because of its unique coiling design. The railing that the roller car rode on was made from copper tubing and the stand which held it up was made up from PVC tubing. I made a actual rolling cart rather than a marble. The roller car uses roller skate bearings to ride the rail with and a compartment made of Legos held some more bearings as weight. We also had a pulley with two chain links hanging from it as a back up car. Both the pulley and bearings car work perfectly. The weight became a huge factor to keep the coasters momentum throughout the track. Some re designing had to be done to make the rail balanced and keep the cars moving.
