GUIDES  
1  Simple Harmonic
Motion Examples Definitions of quantities, explanations of equations, and worked out example problems. 
2  Hooke's Law Hooke's Law seems simple. Why is it so and what are the limits of its application? 
3  Simple Harmonic
Motion What kinds of bodies undergo SHM? What are the characteristics of SHM? 
4  Superposition
and Interference What happens when two waves get to the same place at the same time? The 1D case is studied. 
5  Harmonics Fundamentals, overtones, harmonics: it's all here in graphic detail. 
6  Advanced Waves Examples Definitions of quantities, explanations of equations, and worked out example problems.

3 
Kinematics in the Spring Track the position of a simple harmonic oscillator and analyze the motion. 
4 
Spring
Circuits Springs in series and parallel: how do you determine the "equivalent spring constant"? 
5 
Fork
It Over Determine the speed of sound with a tuning fork, some water, and a pair of plastic tubes.
