Chapter 15 Oscillations and Waves

← Back to document page

A simple harmonic oscillator can be described mathematically by: ( ) ( ) ( ) 2 x t = Acos ωt dx v t = = -A ωsin ωt dt dv a t = = -A ωcos ωt dt Or by: ( ) ( ) ( ) 2 x t = Asin ωt dx v t = = A ωcos ωt dt dv a t = = -A ωsin ωt dt where A is the amplitude of the motion, the maximum displacement from equilibrium, A ω = v max, and Aω2 = a ...
