Today we used circles to model simple harmonic motion, which gave us some equations for the position, velocity, and acceleration of an object undergoing SHM. We also talked about angular frequency.
Notes ended up on the board (below) and we used these sites to look at the motion:
If we had time we also watched this (just because it's cool).
Suggested homework is Chapter 13 (p. 467) #12, 18, 22. This was actually the wrong set, but by the time I realized that it was too late to change, so we're going with it. But next year...#18, 22, 28
