The periodic time of a particle moving with simple harmonic motion is the time taken by a particle for one complete oscillation.

The periodic time of a particle moving with simple harmonic motion is directly proportional to its angular velocity.

The velocity of a particle moving with simple harmonic motion is zero at the mean position.

The acceleration of the particle moving with simple harmonic motion is maximum at the mean position.
