A demonstration helps students understand a principle of roller coaster design. An image of this is shown below. Which answer choice correctly describes the balls kinetic and potential energy
The balls on the roller coaster track illustrate the concepts of kinetic and potential energy. As the balls move down the track, they are converting their potential energy (energy stored due to their position) into kinetic energy (energy of motion). At the top of the track, the balls have the highest potential energy and the lowest kinetic energy. As they move down the track, their potential energy decreases while their kinetic energy increases. At the bottom of the track, the balls have the highest kinetic energy and the lowest potential energy. This demonstrates the principle of the conservation of energy in roller coaster design.
