Question

A boy tries to push a truck parked on the roadside. The truck does not move at all. Another boy pushes a bicycle. The bicycle moves through a certain distance. In which case was the work done more : on the truck or on the bicycle ? Give a reason to support your answer.

Answer 1

Work done = Force $\times$ Displacement
More work is done on the bicycle. This is because the bicycle moves through a certain distance on applying force; No work is done on the truck because it does not move at all on applying force.
