Section 2Measuring simple harmonic motion
Amplitude, Period and Frequency
Amplitude, Period and FrequencyPeriod and frequency measure time.
f = 1/TT = 1/ f
Amplitude measures displacement from equilibrium position.
The period of a simple pendulum depends on string length and free- fall acceleration.
Formula: Simple Pendulum
Where: T = period L = length of string g = free – fall acceleration ( 9.81
m/s2)

Formula : Mass- Spring SystemPeriod of a mass-spring system depends on
mass and spring constant.
Where : T = Periodm = mass k = spring constant
