Forms of Energy, Kinetic Energy Theorem (I)

This lecture covers the different forms of energy, including kinetic and gravitational potential energy, and introduces the concept of energy conservation in isolated systems. It explains how energy can change forms over time, using examples like the simple pendulum and elastic collisions. The lecture also discusses the transformation of kinetic energy into potential energy and vice versa, as well as the dissipation of energy into thermal energy during rebound. The kinetic energy theorem is presented, illustrating how the kinetic energy of an object in motion is related to the work done on it. Various examples and experiments are used to demonstrate these concepts.
