# Simple Harmonic Motion Problem

1. What is the difference between ψ = A

_{mod}(t) cos (w_{av}t)and the simple harmonic oscillator?3. A. The amplitude is time dependent

B. The amplitude,A_{mod} , is twice the amplitude of the simple harmonic oscillator, A.

C. The oscillatory behavior is a function of ? instead of the period, T.

I’m not sure what the difference is. I thought that the equations are similar but that was incorrect.
