Solution 1
Free vibrations are produced when a body is disturbed from its equilibrium position and released.

The vibrations of a body in the absence of any external force on it are called free/natural vibrations.
For example, when we strike the keys of a piano, various strings are set into vibration at their natural frequencies.
