Week 6: Oct 12-16

Dr. Broccio
Physics 0110, Tuesdays at 6

I had one student come to my office hours twice this week. We talked about uniform circular motion and the various conceptual issues that accompany it. Specifically, I drew on the board a circle and various paths that a rock would "fly off" the circle. E.g. it would curve, go straight at a slope, go tangent, etc. We talked about why it flies of tangent every time. Then, we talked about the difference between the tangential velocity and the angular velocity. For several of the homework problems, it was important to realize that the tangential velocity changes depending on the radius, but the angular velocity does not.
