Transcript

I wonder how many 45-pound plates I could put on before the barbell would flip up. Let’s see, moment is force time’s length of lever arm. Wait, no, I wasn’t gonna… I could cross and then turn. But the straightest distance between two points? Officer Pythagoras made me do it. What’s the actual difference between taking one step at a time or two? Hmm. Work is force times distance and my weight isn’t changing. Uh, bending my knee more changes the moment arm, I wonder what normal person heads are like.
