Well, this chapter we were talking about planetary gravitation and all that stuff, and I was all like "how am I supposed to write a blog about that?" So I'm not going to write a blog about that, I'm going to write about torque again. And the subject is Figure skating, since I was watching football, and accidentally went up a channel to figure skating. And as I watched it, the dude did one of those things where they curl up and spins super fast. And then to slow down, he put his arms and leg out and slow his spinning. Torque is how it works. If he were to spin with a large radius , he would go slower since the force would be the same, but the torque would be greater. If he compacts his body, the radius gets smaller, and the torque gets smaller, so he is able to spin faster. Exactly why, I'm not sure, but it has something to do with center of mass and gravity...Which reminds me, I have to do my problem set. (I'm not going to say it this time, Tracy).
