From StarTalk.

How does a collision cause an explosion? Neil deGrasse Tyson and Chuck Nice explain elastic versus inelastic collisions. Why do some objects bounce and others don’t?

We break down different types of elastic and inelastic collisions. Where does the kinetic energy go? Learn the physics of rollercoasters, car accidents, and how meteor impact result in a giant explosion.
