Zero work

Vedclass · Answer

(C) Work done $(W)$ is defined as the product of force $(F)$ and displacement $(s)$ in the direction of the force,given by the formula $W = F 	imes s 	imes \cos(	heta)$.Since the person fails to move the heavy mass,the displacement $(s)$ is $0$.Therefore,the work done is $W = F 	imes 0 = 0 	ext{ Joules}$.Thus,the work done by the person is zero.

$A$ person continues to push a heavy mass for some time but fails to move it. What is the work done by him?
