a. Sharon reminded Bruce that the basketball had energy as it fell. This energy of motion is called kinetic energy. Bruce agreed and said this energy of motion was greatest right before the ball hit the ground.
b. Then Bruce recalled that the ball originally had stored energy as it sat on the wall. This stored energy is called potential energy. Sharon explained that this stored energy lowered as the ball fell.
The basketball is sitting on the wall.
- potential energy
The basketball is falling and is about halfway between the top and the bottom.
- potential energy
- kinetic energy
After the basketball hits the ground, it starts rolling across the ground in front of the wall.
- kinetic energy
