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.
The boy pushing the truck does no work as the displacement is zero (no motion of the truck). But, when the boy pushes the bicycle, work done is more as the force applied by him causes displacement (motion of the bicycle).
