Section 2 Measuring simple harmonic motion

Amplitude, Period and Frequency

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.

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

Guided Practice Open books to pg. 448 Sample Problem 12B

Formula : Mass- Spring System Period of a mass-spring system depends on mass and spring constant. Where :T = Period m = mass k = spring constant

Guided Practice Open Books to pg. 450 Sample Problem 12C
