Then Bruce recall that the ball originally has stored energy as it sat on the wall the stored energy is called potential or kinetic energy Sharon explained that this store energy increase decrease or stayed the same as the ball fell

Answer 1

Bruce realized that the ball originally had potential energy as it sat on the wall. As the ball fell, this potential energy transformed into kinetic energy. Sharon explained that the amount of stored energy decreased as the ball fell due to the conversion from potential to kinetic energy.
