What do you understand by free vibrations of a body? Give one example.
What do you understand by natural vibrations of a body? Give one example.
उत्तर १
Free vibrations are produced when a body is disturbed from its equilibrium position and released.
उत्तर २
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.
