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).
Homework is Chapter 13 (p. 467) #12, 18, 22
