Week of 11/6

This week, the homework of the class I am working with concerned rotation. The fact that you can pick any fulcrum in as system seems to be a tricky concept for students. Also, they aren't seeming to grasp what a moment of inertia is intuitively. I am predicting that there will also be trouble distinguishing between angular and linear values. However, the similar properties of torque and forces (and the laws the go with them) seem to be intuitive. The test is next week and all of the students seem to be a bit nervous for it. However, I think this test will have a higher average than the first one.
