Conservation of Energy: Pendulum Example

This lecture introduces the concept of conservation of energy, focusing on the example of a simple pendulum. It explains how the energy of a system can change forms over time, such as kinetic energy transforming into potential energy and vice versa. Various forms of energy are discussed, including kinetic, gravitational potential, electrical potential, elastic potential (spring), thermal, hydraulic, chemical, electromagnetic (light), nuclear, mechanical, and rotational energy. The lecture emphasizes that in a closed system, energy is conserved, highlighting the continuous transformation of energy in the simple pendulum example.
