PHYSICS BEHIND ROLLAR COASTER

  I go to wonderland often because of the rollar coaster. I am a really big fan of rollar coaster, but I haven't known about the physics behind rolllar coaster before the physics class.

  The physics in the rollar coaster is due to the gravitational force and the apply force acting on it. The friction in the rollar coaster is also an very important part of a rollar coaster. Without friction, the rollar coaster might not able to stop and the people wouldn't be able to step forward. Anthor physics behind rollar coaster is the energy of the collar coaster. As we know, Many energy in acting on an obect, the most affective energy that act on the collar coaster would be potential energy and the kinetic energy. As the rollar coaster is pulled on the top, a porential energy is created and once the rollar rolls from the top, the potential energy would transferred to both kinetic and potential energy.
