//Talking about normal force and sleds Schafer: So my kids will be like, 'Dad! Can you push our sled?' And I'll be like 'No.' And before you say that I'm a terrible parent, hear me out. I told them, 'I will not push your sled because if I push, the force vector will not only have a horizontal component but also a vertical one downwards which would lead to increased friction cue to more normal force and thus you would go slower. But I will pull your sled, because that vector points up.' Student 1: And the sled would hit your shins. Schafer: Well actually, I tie this big long rope around my waist and I walk. And then the kids fall off, and I just keep walking.

Schafer: So there are 2 things about my kids that I'm really proud of. So the first thing is that they both could ride a bike, no training wheels, by the time they were 4. //class murmurs, impressed Schafer: The second thing is that, when they were first learning how to speak, whenever they saw a small dog they'd both say "kitty cat!"
