Answer
... Work done by the force of gravity on an object depends only on vertical displacement. Vertical displacement is given by the difference in the initial and final positions/heights of the object, which is zero. Work done by gravity is given by the expression, W= mgh Where, h= Vertical displacement = 0 ...
