Today, we'll start by doing a daily quiz on oscillations.  In the quiz, we'll be reviewing many different aspects of oscillations including kinematic variables, forces, and energy in an oscillating system.

Then, watch the following video explaining the calculus of solving simple harmonic motion.  This video is really similar to the lecture I would have given in class.  This is one of the videos I would really pay attention to!  There's a lot of important information packed in here!  Watch it slowed down, pause to think about the analyses (especially in the graph section at the end), and watch it multiple times!

Homework:  Watch the following two videos on simple harmonic oscillators with springs and pendulums.  Alternatively, learn about simple harmonic oscillators using the available media of your choice - textbook, internet, etc.

SHM: Pendulums (Dan Fullerton)

Small angle approximation:  For small angles θ (in radians) ≈ sin θ ≈ tan θ :
