Angular Momentum, Hooke's Law and SHM

In this lecture we concluded our discussion of rotational motion by looking at the conservation of angular momentum. We then proceeded to the next chapter on simple harmonic motion. We began with the study of spring forces. Adding a mass to a spring and moving it from its equilibrium position will lead to oscillations about the equilibrium point. We looked at the sinusoidal behavior of this motion and derived the expression for the frequency of oscillation. Knowing the frequency, we can get the period.
