Asked by Julie
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 total energy of the system remains the same.
The total energy of the system decreases.

The total energy of the system remains the same.
Energy is conserved. If the ball gains kinetic energy, that energy must come from somewhere: the club loses kinetic energy or energy is supplied by the golfer doing work on the club (chemical → mechanical). In a real collision some mechanical energy can be converted to heat/sound, so the mechanical energy of club+ball can decrease, but the total energy (all forms) does not spontaneously increase.
