Work, Energy, and Power

This lecture covers the concepts of work, energy, and power in physics, focusing on the calculation of work done by forces, the kinetic and potential energy of objects, and the distinction between conservative and non-conservative forces. The instructor explains how to calculate the work done by gravity in different scenarios and introduces the concept of mechanical energy. The lecture also delves into the conservation of mechanical energy and the relationship between kinetic and potential energy. Various examples are provided to illustrate these concepts.
