A restoring force is a must for a body to execute S.H.M. Explain why.

Is restoring force necessary in S.H.M?

Derive by method of dimensions an expression for the energy (E ) of a body executing SHM assuming that this energy depends upon (i) the mass (m), (ii) the frequency (v) and the amplitude of vibration (gamma) .

In an oscillating circuit, the resttoring force is must. In and LC-circuit, the restoring force is provided by

Draw time-displacement curve for a body moving in S.H.M.

A constant retarding force of 50 N is applied to a body of mass 20 kg moving initially with a speed of 15m s^-1 . How long does the body take to stop ?
