What is meant by maintained oscillation ? Given an example.

Explanation

(ii) While playing in swing , the oscillations will stop after a few cycles , this is due to damping . To avoid damping we have to supply a push to sustained oscillations . By supplying energy from an external source , the amplitude of the oscillations can be made constant.
(ii) Such vibrations are known as maintained vibrations.
Example : The vibration of a tuning fork getting energy from a battery or from external power supply .
