Elastic and Inelastic Collisions: Momentum, Energy Conservation, and Frame of Reference
This PowerPoint focuses on elastic and inelastic collisions, starting with one-dimensional elastic collisions where mechanical energy is conserved. It explains the conservation of momentum and how, in elastic collisions, equal masses bounce back with reversed velocities. For inelastic collisions, momentum is conserved, but kinetic energy is not. The presentation also covers the center of mass (CM) and its movement during collisions, including the behavior in both the lab and CM frames. It highlights how, in elastic collisions, the velocities in the CM frame are reversed. Two-dimensional collisions and complex problems involving momentum and energy conservation are also discussed.
