What name is given to the maximum displacement of a vibrating body from its central position ?
The maximum displacement of a vibrating body from its mean position is called Amplitude.
The diagram in Fig. 7.13 shows the displacement-time graph of a vibrating body.
(i) Name the kind of vibrations.
(ii) Give one example of such vibrations.
(iii) Why is the amplitude of vibrations gradually decreasing ?
(iv) What happens to the vibrations of the body after some time ?
