Anya lifts a ball high above her head and drops it. the ball bounces up and down. she observes that the ball loses height every time it bounces. how can this situation be explained? some of the ball’s energy changes to thermal energy when it hits the ground. the ball loses some of its energy to the force of gravity. there’s no air resistance (drag) on the ball. the mass of the ball changes with each bounce.
