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 the 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.
