Chapter 8 Potential Energy and Conservation of Energy
... When the mechanical energy of a system is conserved, we can relate the sum of kinetic energy and potential energy at one instant to that at another instant without considering the intermediate motion and without finding the work done by the forces involved. As a pendulum swings, the energy of the ...

... Example: throw a tomato upward. When the tomato goes upward, the gravitational force does negative work, decreasing its kinetic energy: the kinetic energy is transferred by the gravitational force to the gravitational potential energy of the tomato-Earth system. When it goes downward, the gravitati ...
