Detailed Solution

The moon is experiencing a gravitational force due to the earth and is revolving around the earth in a circular orbit. The work done by the moon is 0.
The work done by the moon is zero because the gravitational force acts towards the centre of the orbit and the displacement is in the tangential direction. The angle between the force and displacement is 90°.
we know work done is
W=F s cos θ

        F is the force applied


        d is the displacement


        θ is the angle between the force and displacement vectors.


 W=F s cos 90°
 W=F×s×0 (as cos 90°=0)
 W=0
