Potential Energy and Conservation of Energy

This lecture covers the concepts of potential energy, energy conservation, power, and force in the context of mechanics. It explains how potential energy is stored by objects due to work done by conservative forces, and how energy is conserved in various processes. The instructor also discusses the relationship between force and potential energy, as well as the use of potential energy diagrams to visualize energy changes. Additionally, the lecture explores the conservation of mechanical energy and provides examples of conservative and nonconservative forces. The session concludes with demonstrations illustrating the principles of energy conservation in practical scenarios.
