Advanced Physics I: Energy and Collisions

This lecture covers the concepts of energy in a system of particles, including the energy of a particle system, conservative internal forces, and examples of energy conservation in collisions. It also delves into the analysis of collisions between multiple bodies, defining the term 'collision' and exploring the impact of forces during collisions. The lecture further discusses systems of variable mass, focusing on the energy and momentum of such systems, and concludes with a detailed examination of elastic and inelastic collisions.
