<P> where K is kinetic energy , m is mass , and v is velocity . Because the mass of a roller coaster car remains constant , if the speed is increased , the kinetic energy must also increase . This means that the kinetic energy for the roller coaster system is greatest at the bottom of the largest downhill slope on the track , typically at the bottom of the lift hill . When the train begins to climb the next hill on the track , the train 's kinetic energy is converted back into potential energy , decreasing the train 's velocity . This process of converting kinetic energy to potential energy and back to kinetic energy continues with each hill . The energy is never destroyed , but is lost to friction between the car and track . Brakes bring the ride to a complete stop . </P>
