Amplitude

Hello,

I am stuck on some definitions.

Vibration Amplitude ... Does this mean the amplitude of the position? So the distance from equilibrium to A/- A?

Acceleration amplitude .. So this means the amplitude of the acceleration graph? or Aw^2?

Thanks,

You are right. For vibration amplitude, it is found in displacement time graph and it is the distance from equilibrium to the maximum displacement.
For acceleration amplitude, Aw^2 is one way. But graphically, it is found in acceleration time graph and it is the maximum acceleration from equilibrium.
