Is it possible that a body be in accelerated motion under a force acting of the body, yet, no work is being done by the force ? Give example.

Text Solution

Verified by Experts

Yes , it is possible when a force is perpendicular to the direction of motion. For example, the moon revolves around the earth under centripetal force of attraction of the earth but the earth does no work on the moon.
