No,it is independent of time.

Vedclass · Answer

(B) The work done $(W)$ in raising an object vertically is given by the formula $W = mgh$,where $m$ is the mass of the object,$g$ is the acceleration due to gravity,and $h$ is the height to which the object is raised.Since the work done depends only on the force applied (which is equal to the weight of the object,$mg$) and the displacement $(h)$,it is independent of the time taken or the speed at which the object is raised.Therefore,the work done does not depend on how fast the object is raised.

Does the work done in raising an object vertically depend upon how fast it is raised?
