Physics of Energy: Gravitational Potential Energy

This lecture discusses the concept of gravitational potential energy, which is the energy possessed by an object at a certain height. It covers the relationship between kinetic and potential energy, work done by gravitational forces, and the conservative nature of gravitational forces. The lecture also explores the definition of mechanical energy, emphasizing the difference between conservative and non-conservative forces. Additionally, it delves into power as a measure of work done per unit of time and explains the concept of efficiency in energy transformations.
