Potential Energy and Conservation of Energy

This lecture covers the concepts of potential energy, energy conservation, power, force, and energy diagrams. It explains how to calculate potential energy, the relationship between force and potential energy, and the conservation of mechanical energy. The instructor discusses the different forms of energy, the demonstration of conservation of energy, and the tension in a pendulum. The lecture concludes with a conceptual question on the highest speed on a frictionless hill and the height of a dart shot from a spring-loaded toy gun.
