When a rubber ball bounces against a hard surface, it will bounce and follow a pattern similar to the picture below. Which answer choice best explains the energy transformation occurring in this system? 7.P.11.2
When the ball is dropped, it has high kinetic energy and low potential energy. As it falls, the kinetic energy transforms into potential energy. Some energy is destroyed in the bounce, resulting in a shorter bounce each time.
