//Talking about gravitational pull Schafer: So if Alan and Shariar are one meter apart, the gravitational pull would be- //Alan scoots closer to Shariar //Shariar sits awkwardly Schafer: Or... half a meter. That works too. And since we're already awkward, lets get more awkward. Let's say each of you are 100 kg. Which I know is not true, because you'd be over 200 lbs. Are you accelerating towards each other? Class: Uh... Schafer: Yes! But the gravitational pull is so little you cannot see it. Student: Could Shariar be accelerating away? Scafer: Well, there are both attractive and repulsive forces... Class: Ooh...

//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.
