What Happens When Two Things Collide

This selection will show you what happens when two objects crash into each other, or collide.

A collision between two objects involves two things: how much mass each object has, and how fast it is going when it entered the collision.

This page will allow you to set up your own crash movie by selecting different vehicles and speeds. Fasten your seat belt!
