From the work-energy theorem and the relationship between work and potential energy, we have: ΔK=−ΔU. Rearranging this, we get: ΔK+ΔU=0. This implies that the change in the total mechanical ...

This test covers work done by a force, kinetic Energy, potential Energy and Work-Energy Theorem. Q1. A bus can be stopped by applying a retarding force F when it is moving with speed v on a level ...
