Classes on April 13, 2015

For periods 1-2 and 8-9:

Check out the quiz from before break, and talk through anything you may have missed with others in class. Then, check out and take notes on a video on something called the parallel axis theorem. This is a neat 'trick' for finding moments of inertia of objects, where the axis of rotation is NOT the center of mass, without having to do an integral - the only thing you need to know is the 'normal' moment of inertia for an object, where the axis of rotation is the center of mass. This can be useful for trickier problems and situations.

Next, check out an introductory video for simple harmonic motion. Take good notes, since the homework set will be based on the results.


For Periods 3-4:

Check out the quiz from before break, and talk through anything you may have missed with others in class. Then, check out a video (and take notes) of finding the flux via an integral. Next, check out an introductory video for our last type of circuit, where an inductor and capacitor are combined into a LC circuit. The homework set has to do with these two videos, so, again, take good notes. We will pick up on all this Tuesday.
