Learn how to calculate the vector change in momentum of a bouncing ball in this physics tutorial! This video explains the concepts of momentum, direction, and collisions step by step, making it easy ...

Back in the fall of 1989, I was a freshman at Williams College, and one Monday night that fall there was some sort of problem with the cable TV in our dorm, so a bunch of us went next door to watch ...

First, in my defense I was just making a model based on the data I had. Of course, I am talking about my first super bounce ball post. Just to get you up to speed, I wanted to see how fast you would ...

Model: This is some type of representation (conceptual, mathematical, physical, computational) of a real object. Example: a model of a bouncing ball would produce results that agree with a real ...

Back on Sunday, I devoted a "Football Physics" post to talking about erratic bouncing and an amazing rugby play where a ball popped up high at just the right moment. That's the sort of play that ...
