Question

A mass of 10 kg is at a point A on a table. It is moved to a point B. If the line joining A and B is horizontal, what is the work done on the object by the gravitational force? Explain your answer.

Answer

The work done by the gravitational force acting on the body is zero because the force acts vertically downward, while the displacement is horizontal. Since the force and displacement are perpendicular to each other, no work is done by gravity in this case.
