The maximum amplitude is independent of the natural resonant frequency. 1 Hz on the horizontal. If you suspected that this graph has an uncanny similarity to the displacement graph, you are correct. They are mirror images of each other. Displacement has a near flat response below resonance.
Acceleration has near flat response above resonance.
We see in these two cases that the Q determines the ratio of 'amplitude at ' to 'amplitude in the flat region of response'. Only experience can help us here. The velocity graph has a simple mathematical form, but it has few analytical points we can use to remember its shape. Q has the effect of reducing the peak at resonance.
