When its acceleration is at its greatest, its velocity is zero. Its greatest velocity is equal to its maximum acceleration.
Simple harmonic motion is periodic motion caused by a restoring force that is proportionate to the deviation from equilibrium.
Simple harmonic motion is periodic motion, but many other conditions are dependent.
Simple harmonic motion is periodic motion under the action of a restoring force that is directly proportional to the displacement from equilibrium.
A system that undergoes periodic motion always has a stable equilibrium position.
Hence,when its acceleration is at its greatest, its velocity is zero. Its greatest velocity is equal to its maximum acceleration.
