Work Energy proof part 3 - Elastic Energy

The video tutorial provides a detailed proof of the work-energy formula, focusing on elastic energy. It simplifies the problem to a one-dimensional case to calculate the work done by a spring force using Hook's Law. The tutorial explains the integral approach to derive the work done and discusses the generalization to higher dimensions. The concept of elastic energy is introduced, and the relationship between kinetic energy, gravitational potential energy, and elastic energy is explored. The video concludes with a promise of further exploration in a subsequent video.
