Physics of Rollercoasters:

Roller coasters use all sorts of energy they use potential energy on the climb up the hill on the rollercoaster. They also use gravitation, free fall, and velocity on the way down the hill and onto the next. They use projectional motion for when the rollercoaster goes down a small roller coaster. The next thing is acceleration which is used when a roller coaster is designed to go upside down. When the roller coaster is designed to go up a loop they use friction and also magnetic inside the coaster tracks. acceleration stress is when a sudden increase of speed.external image dragster.jpg

This roller coaster (right) can sky rocket up to 120 mi. per hour. It can fly 400 ft tall which makes a roller coaster record. The top thrill dragster is located in Sandusky, OH at Cedar Pointe.

two roller coasters are called the great bear and the sidewinder at hershey park in hershey PA.some other rollercoasters are the raptor the storm runner top thrill dragster the maverick and the new mellanium . some roller coasters have hydrollics that push them really fast and others just have a chain that pulls them up hills. the fastest roller coaster is the top thrill dragster it goes 120 miles per hour and is 400 FT. tall and it is the tallest in the world.
