Overview of Angular Momentum

Angular momentum is pretty straightforward except for one little detail: it's kind of funky that you can calculate the angular momentum of an object that's moving in a straight line. Like you could willy nilly calculate the linear momentum of the next jogger you see run past you. Even crazier, since the jogger ins't rotating, you can pick any axis you want, potentially making their angular momentum HUGE if you pick an axis a block away. This video explains that.
