Respuesta :
A roller coaster shows potential and kinetic energy because as the roller coaster goes down a hill and it is moving, it shows kinetic energy. (Kinetic energy-The energy of Motion) As the roller coaster is at the top of a hill and is not moving down yet, it shows potential energy. This is because the roller coaster is not moving yet, but is about to exert energy. (Potential Energy-The energy that is stored in an object that is not moving.)
On a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. Kinetic energy is energy that an object has as a result of its motion. All moving objects possess kinetic energy, which is determined by the mass and speed of the object.
