Question
Give an example when work done by the force of gravity acting on a body is zero even though the body gets displaces from its initial position.
✓

Answer

When a coolie carries a load while moving on a ground, the displacement is in the horizontal direction while the force of gravity acts vertically downward. So the work done by the force of gravity is zero.
