// Pd. 6 Freshman Physics, Schafer is talking about “bouncy” (elastic) and “sticky” (inelastic) collisions Schafer: Really every collision is some amount inelastic, so it’s not perfectly bouncy or sticky. Schafer: If you’re playing football and you run into someone there’s a sort of bounciness effect. Ari: people are bouncy! Schafer: ~some~ people

// Pd. 6 Freshman Physics Schafer: Now I’m going to demonstrate an explosion. It’s not very loud or exciting. But still, this is probably the only explosion you’ve seen at school today, and the coolest part of your day.

// Pd. 6 Freshman Physics Schafer: Everyone, say it: MMMomentum! So, what letter should we use to represent MMMomentum? Schafer: It’s P. Schafer: So from now on we’re going to call it pmomentum. // A few minutes later Schafer: Why is impulse written with a J? Now Michael said “jimpulse” would sound pretty ridiculous but “impulse” is from Latin. So is Spanish, and impulse in Spanish is “jimpulse” and if anybody here knows Spanish you know it’s pronounced [with the soft J]. Schafer: that’s actually all a lie but it’ll get you to remember it

Michael: Just saying. That dog looks like one of Picasso's cats. Michael: ...That's not a compliment, by the way. Schafer: I know. If you were my ear, I would make like Van Gogh. Schafer: ...That's not a compliment, by the way.
