Question
Taro stated that when someone hits a golf ball with a club, the amount of energy the ball has changes, the amount of energy that the club has changes, and the total energy of the system that includes the ball and the club increases. Which best explains Taro’s error?

The amount of energy that the club has does not change.
The total energy of the system remains the same.
The total energy of the system decreases.
The amount of energy that the ball has does not change.
The amount of energy that the club has does not change.
The total energy of the system remains the same.
The total energy of the system decreases.

The best explanation for Taro's error is: **The total energy of the system remains the same.**
According to the law of conservation of energy, the total energy of a closed system remains constant. When the golf ball is hit by the club, energy is transferred from the club to the ball, resulting in changes to the energies of both, but the total energy of the system (club + ball) does not increase; it remains constant, assuming there are no external forces doing work on the system (like friction or air resistance).
