» Oscillations and Waves » Simple Harmonic Motion » Force, Velocity, and Acceleration

Assertion-Reason▾

Assertion (Ꭺ)

Consider motion for a mass spring system under gravity, motion of M is not a simple harmonic motion unless Mg is negligibly small.

Reason (Ꭱ)

For simple harmonic motion acceleration must be proportional to displacement and is directed towards the mean position.
