Question
When you push your bicycle up on an inclined plane, the potential energy of the bicycle and yourself increases. Where does this energy come from?
Short Note
Solution
When a person pushes his bicycle up on an inclined plane, the potential energies of the bicycle and the person increase because moving up on the inclined plane the kinetic energy decreases. and as mechanical energy is sum of kinetic energy and potential energy, and remains constant for a conservative system. Therefore, potential energy must increase in this case.
