Question

When a body like earth is moving in a circular
path the work done in that case is zero because?​

Answer 1

Answer:

The work done on a body moving in a circular path is also zero. This is because, when a body moves in a circular path, then the centripetal force acts along the radius of the circle, and it is at right angles to the motion of the body. Thus, the work done in the case of moon moving round the earth is also zero.

Answer 2

Answer:

because centripetal force acts in the direction of motion of the body. centripetal force acts along the radius of the circular path. gravitational force acts along the radius of the circular path.
