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 transformed into kinetic energy as the ball fell.
c. The basketball is sitting on the wall.
- Potential energy: The basketball is sitting on the wall.
The basketball is falling and is about halfway between the top and the bottom.
- Potential energy: The basketball is falling and is about halfway between the top and the bottom.
After the basketball hits the ground, it starts rolling across the ground in front of the wall.
- Kinetic energy: The basketball is rolling across the ground in front of the wall.
Sharon and Bruce are playing basketball at a local park. When they take a break, they put the basketball on the brick wall that is near the bleachers.
