Question

Differentiate between forced oscillations and supported oscillations.

✓

Answer

Under the influence of an external induced force, a body which oscillation with a frequency other than its natural frequency called forced oscillation if the energy is replenished at the same rate at which the oscillator's energy is lost, then the amplitude of oscillation remains unchanged. Such oscillation are called supported oscillations. For example, the oscillations of a pendulum clock or the movement of the balance wheel of a wrist watch are examples of supported oscillations.
