Question

(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?

Answer 1

(i) It is damped oscillation

(ii) A block attach to the spring, and the system placed horizontally on rough surface. Giving a small amplitude will start oscillation but amplitude gradually reduce to zero.

(iii) In damped motion energy of system decreases with time due to which amplitude reduce with time

(iv) After some amplitude gradually reduce to zero, and oscillation stop.
