Forces and Energy Conservation

This lecture covers the concept of forces and energy conservation, focusing on conservative forces and potential energy. It explains how work is related to the difference in potential energy and how to calculate it using graphs. The instructor demonstrates the work done by elastic forces and the conservation of energy in different scenarios. The lecture also delves into the concept of gravitational potential energy and how it is defined relative to a reference point. Various examples are provided to illustrate the calculations and applications of energy conservation.
