The Physics Philes, lesson 31: Please, Control Your Impulses

In which balls are thrown, calculations are made, and further explanation is required. Last time on The Physics Philes, we started discussing momentum and impulse. This week we’ll do an example problem, but before we begin I need to add a bit of information. As I was preparing for this …


The Physics Philes, lesson 30: Return of Physics!

In which tennis balls are hit, momentum is gained, and physics is resurrected. Lately I’ve been doing a lot of math in this small corner of the Internet. Well, trying to, anyway. But then I realized, hey! This is The Physics Philes, not the Math…Thingy. So this week we see …
