The Physics Philes, lesson 61: Don’t Be So Rigid

Up off your bums, boys and girls. It’s physics time. Last week we started a more in depth discussion of angular momentum. This week, as promised, we will dive into angular momentum of a rigid body. Remember when we figured out the angular momentum of a particle equals the product …


The Physics Philes, lesson 52: Torque, This is Your Moment (of Inertia)

Oh. My. Glob. This is week 52. Fifty-two weeks (give or take a couple) of studying physics. It’s been, at various times, frustrating, fun, and rage-inducing. But it’s mostly been a hoot and a half, and I’m nowhere near done. So! Let’s get on with it! As promised, this week …
