Definition: Any motion where the restoring force is directly proportional to the distance away from the equilibrium position. (Typically a pendulum or a mass on a spring)

Acceleration is greatest when the object is furthest from its equilibrium position – Why does this make sense?

A definition: Any motion that repeats itself over and over again Periodic Motion A definition: Any motion that repeats itself over and over again

A Pendulum exhibits simple harmonic motion and periodic motion

Why is simple harmonic motion which is clearly linear in the case of a mass on a spring described with rotational motion formulas?

The formulas for Simple Harmonic Motion:

Formulas

A pendulum makes 30 complete oscillations in 20 seconds: what is the period of 1 oscillation? What is the frequency of the pendulum? What are the units of frequency?
