044 - Simple Harmonic Motion

In this video Paul Andersen explains how simple harmonic motion occurs when a restoring force returns an object toward equilibrium. The two types of harmonic motion studied in AP Physics are the mass spring oscillator and the simple pendulum. The period of a mass spring increases as the mass of the object increases and decreases as the spring constant increases. In a simple pendulum the period increases as the length increases and decreases with an increase in the gravitational field strength.
