Period:

The period of harmonic motion is the time it takes for one complete cycle or oscillation.

Amplitude:

The amplitude of harmonic motion is the maximum displacement from the equilibrium position.

Frequency:

The frequency of harmonic motion is the number of complete cycles or oscillations per unit of time.
