Question

“The revolution of the moon around the earth”. Here, the work done by the gravitational force exerted by

the earth is zero because the displacement of the moon is at ............... to the direction of the earth’s

gravitational force​

Answer 1

The work done by the moon during one circular motion is zero as the force acting between the earth and moon is gravitational force is conservative in nature and the work done by conservative forces does not depends on path followed. Also the force and displacement are perpendicular to each other. So, work done is zero.
