At a vibration is generally referred to the instantaneous distance x of the point P ( at a curve or straight line) from its rest position as the displacement or elongation. The largest deflection or elongation is referred to as amplitude.

For example, the amplitude of the Schallauslenkung ξ (Greek Xi) a harmonic oscillation:
