Question

Give example of a situation in which an applied force does not result in a change in kinetic energy.

Answer 1

Assume a ball tied to a string and is moving in a verticle circle.Work done bytension force will be zero and hence tension forcewill not cause any change inKE of ball.

Answer 2

Explanation:

Assume a ball tied with a string which is moving in a vertical circle work done by tension force will be zero and the tension force will not gain any change in KE. of ball.
