Motion and potential energy graphs
... Consider a body of mass m that is subjected to a single conservative external force. The body will speed up and slow down in such a way that its total mechanical energy is constant. We can qualitatively assess what motion is possible by examining a graph of potential energy. For concreteness, we con ...
