The motion of a ball with a mass of 500 g which is dropped to fall freely to the ground, is observed. It bounces off the ground and does not reach the initial height.
Explain how the energy of the ball changes as it falls.
Why doesn't the ball reach the starting height after bouncing off the ground?
Calculate the energy change of the ball if it falls to the ground from a height of 2 m and bounces back to a height of 1.5 m.
