SAQ : Explain whether work is done due to the revolution of the earth around the sun

Question

Explain whether work is done due to the revolution of the earth around the sun.

Answer

No, work is not done due to the revolution of the Earth around the Sun.

Work is a measure of the energy transferred when a force causes an object to move in the direction of that force. When the Earth revolves around the Sun, there is a gravitational force between them, but this force acts perpendicular to the direction of motion. [W = FS cos 90º = 0]
