Elastic and Inelastic Collisions

Mr. Anderson explains the concepts of elastic and inelastic collisions in AP Physics. He uses examples of balls and matchbox cars to illustrate how energy and momentum are conserved or transformed during collisions. Elastic collisions maintain both momentum and kinetic energy, while inelastic collisions only conserve momentum, with some energy converted to internal energy. Simulations demonstrate these principles, showing how to calculate outcomes using conservation laws.

What is the formula for kinetic energy, and how is it applied in elastic collisions?

Describe the outcome of an inelastic collision using the conservation of linear momentum.

What are the implications of losing kinetic energy in a collision?
