1. Section 2 Measuring simple harmonic motion

2. Amplitude, Period and Frequency

3. Period and frequency measure time. f = 1/T T = 1/ f Amplitude measures displacement from equilibrium position. The period of a simple pendulum depends on string length and free- fall acceleration.

4. Formula: Simple Pendulum Where: T = period L = length of string g = free – fall acceleration ( 9.81 m/s 2 )
