I've decided to release some selected (previously unlisted) lecture videos from my calculus classes to the public. I don't plan on doing this for many videos. The main reason I'm doing this is to see how well these lecture videos appear on my cell phone, and to see how many views I get and where the videos show up in search results.
In this video, I discuss torque, a measure of rotational tendency, defined as the cross product of the position and force vectors.
