Conceptual: Collisions

Today we talked about the two kinds of collisions and did some math for inelastic collisions. We also tried out several collisions on an air track. There are some videos of this demo from several years ago on YouTube (thanks to the long-ago-graduated Edgar):

Elastic Collision I
Elastic Collision II
Inelastic Collision

We did several others in class...but I guess you had to be there. Homework this weekend is Concept-Development 7-1.
