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. They notice that the basketball rolls off the wall and falls to the ground. %0D%0A%0D%0A%0D%0A%0D%0AThis makes them think about a school lesson about energy.

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.
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 converted into kinetic energy as the ball fell.
c. In each situation described, the type or types of energy are:
- The basketball is sitting on the wall: Potential energy
- The basketball is falling and is about halfway between the top and the bottom: Both potential energy (due to its position) and kinetic energy (due to its motion)
- After the basketball hits the ground, it starts rolling across the ground in front of the wall: Kinetic energy
a. Sharon reminded Bruce that the basketball had energy as it fell. This energy of motion is called kinetic energy.
To answer this question, we can recall that kinetic energy is the energy possessed by an object due to its motion. In this case, when the basketball fell, it was in motion, so it had kinetic energy.
b. Bruce agreed and said this energy of motion was maximum right before the ball hit the ground.
To answer this question, we need to understand that the maximum kinetic energy of an object occurs when its velocity is highest. In this case, right before the ball hit the ground, it was moving with its maximum speed, so its kinetic energy was maximum.
c. 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.
To answer this question, we need to understand potential energy, which is the energy an object possesses due to its position or state. In this case, when the basketball was sitting on the wall, it had potential energy because of its elevated position. As it fell, this potential energy transformed into kinetic energy of motion.
