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 at its maximum 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 decreased as the ball fell.
If the basketball is sitting on the wall, it possesses potential energy. This is because potential energy is the energy stored in an object due to its position or configuration. In this case, the basketball is elevated above the ground, which means it has gravitational potential energy that can be converted to kinetic energy when it falls.
When the basketball is falling and is about halfway between the top and the bottom, it has both kinetic energy and potential energy.
At this point, the ball has lost some of its potential energy as it descends, which is converted into kinetic energy as it gains speed. The potential energy is lower than when the ball was at the top, while the kinetic energy is higher than when it was at rest on the wall. The total mechanical energy (the sum of kinetic and potential energy) remains constant if we neglect air resistance.
I apologize for any confusion. If we have to choose between kinetic energy or potential energy when the basketball is halfway down, the answer would be that it has kinetic energy at that moment, as it is in motion. However, it still retains some potential energy due to its position above the ground. But if you're only looking for one option, kinetic energy would be the primary focus since the ball is actively falling.
Thank you for your patience! If the option is strictly kinetic energy or potential energy, then when the basketball is halfway down, it primarily represents kinetic energy, since it is in motion as it falls. However, it still possesses some potential energy due to its height above the ground. If you need to select only one, please confirm that you are choosing the option for kinetic energy.
After the basketball hits the ground and starts rolling across the ground, it primarily possesses kinetic energy. This is because it is in motion as it rolls. Once the ball has stopped rolling or is at a height again, it could have potential energy, but while it is moving on the ground, kinetic energy is the dominant form of energy.
