Elastic and Inelastic Collisions

This lecture delves into the concepts of elastic and inelastic collisions, exploring the conservation of momentum and energy in various scenarios. Through practical experiments and theoretical explanations, the instructor demonstrates how different masses and velocities impact the outcomes of collisions. The lecture also covers the transition from mechanical to thermodynamic energy, showcasing examples like a cannon propelled by hydrogen gas and the propulsion of objects using compressed air or water. By analyzing forces, durations of impacts, and energy conversions, students gain insights into the complexities of collisions and the importance of understanding system boundaries and external forces.
