Question
Direction : Is this an example of kinetic energy?
Throwing a ball
- Yes
- No
Hint:
Yes
The correct answer is: Yes
A thrown ball has mechanical energy as the result of both its motion which produces kinetic energy and its position above the ground which produces gravitational potential energy. When the ball is thrown, chemical energy in the muscles of the person is transferred to the ball as kinetic energy.
