My class recently did a roller coaster project on Newton's Laws of Motion. We had to draw a working roller coaster and find out what goes with making roller coasters. Newton's first law says that an object in motion stays in motion unless acted on by an outside force. It also says the same thing about an object at rest. His second law says he acceleration of an object depends on the mass of an object and the size of the net force applied. His third law says that when a force is applied to an object, the object exerts the same force in the opposite direction.
I was in a group of four people. Everybody had their own role in the project. There was the lawyer who needed to find some roller coaster laws and some recent lawsuits or accidents. There was the design engineer who had to find out what roller coasters are made out of and how they make a roller coaster. There was the physicist who had to find out how physics and Newton's Laws went into building the roller coaster. The last role was the historian who was in charge of finding out the history of roller coasters. I was the historian and I found out that the first roller coaster was an ice slide in Russia that was about 70 feet tall.
This roller coaster worked because i successfully changed the potential energy into kinetic energy. I also made sure there was enough friction to stop it successfully.
This roller coaster failed because there was too much energy at the end. It went right through the finish and crashed. The velocity made it speed past the finish. My group chose to call our roller coaster The School Project. We drew it so the carts would be pencils and the track is a ruler. If you want to make your own roller coaster then click here.
