The diagram in figure shows the displacement-time graph of a vibrating body.
(i) Name the kind of vibrations.
(ii) Give one example of such vibration.
(iii) Why is the amplitude of vibrations gradually decreasing?
(iv) What happens to the vibrations of the body after some time?

(i) Vibrations that have been dampened
(ii) Example: When a tuning fork is stroked on a rubber pad, it produces damped air vibrations.
(iii) The frictional force reduces the amplitude of vibrations. The vibrating body’s energy is constantly dissipated as it works against the force of friction. As a result, the amplitude of the signal progressively diminishes.
(iv) When it has used up all of its energy, it stops vibrating.
