Give an example where work done is zero and diplacement is there
A man with a suitcase on his head walking a distance of 10 m.
Here, the force acting is perpendicular to the displacement. Hence, the work done is 0.
Give an example work done by the force of gravity acting on a body is zero even though the body gets displaced from its initial position.
Give an example of a motion in which the displacement is zero, but the distance travelled is not zero.
