The Physics Philes, lesson 34: Worlds Collide

In which billiard balls bounce, cars crash, and kinetic energy is (sometimes) conserved. Over the past few weeks we’ve been discussing momentum and the principle of conservation of momentum. This week we’ll continue on that trajectory and talk about how momentum affects collisions of particles! I know! Exciting, right? Before we jump in, we should probably figure out what we mean when ... »
