Which of the following is an example of kinetic energy transfer? (1 point)
A large snowball
sitting at the top of a
hill
Xavier pushing Brad down the snowy hill on a sled
A car driving up a steep hill
Jules sitting in a chair
Xavier pushing Brad down the snowy hill on a sled
The example of kinetic energy transfer among the options provided is Xavier pushing Brad down the snowy hill on a sled.
To determine which of the following options is an example of kinetic energy transfer, let's first understand what kinetic energy is. Kinetic energy is the energy possessed by an object due to its motion.
1. A large snowball sitting at the top of a hill: In this scenario, the snowball is not in motion, so it does not have kinetic energy. Therefore, this option is not an example of kinetic energy transfer.
2. Xavier pushing Brad down the snowy hill on a sled: In this situation, Xavier pushes Brad, causing the sled to move down the hill. As the sled moves, it gains kinetic energy. Since the movement of the sled involves a transfer of energy, this option is an example of kinetic energy transfer.
3. A car driving up a steep hill: In this case, the car is moving, so it possesses kinetic energy. However, since the car is driving up the hill, the energy transfer involved is potential energy being converted into kinetic energy. Therefore, this option does not demonstrate kinetic energy transfer.
4. Jules sitting in a chair: This option does not involve any form of motion, so there is no kinetic energy transfer. Jules sitting in a chair does not demonstrate kinetic energy transfer.
Based on the explanations given above, the example of kinetic energy transfer is option 2: Xavier pushing Brad down the snowy hill on a sled.
