Answer:
Dropping a stone from a height is work
Explanation:
Work is the action of a force through a distance.
w = fd
The Earth's gravitational attractive force is pulling the stone to its centre, so the Earth is doing work on the stone.
Forces cause acceleration, not motion. The law of action-reaction (Newton's third law) explains the nature of the forces between the two interacting objects. According to the law, the force exerted by object 1 upon object 2 is equal in magnitude and opposite in direction to the force exerted by object 2 upon object 1.
