If a tunning fork is vibrating freely, then its vibration will be:
forced
damped
resonant
natural
When a body vibrates under a periodic force, the vibrations of the body are :
(a) natural vibrations (b) damped vibrations
(c) forced vibrations (d) resonant vibrations.
A wire stretched between the two fixed supports, is plucked exacly in the middle and then released. It executes (neglect the resistance of the medium) :
(a) resonant vibrations (b) natural vibrations
(c) damped vibrations (d) forced vibrations.
A tuning fork is vibrating in air. State whether the vibrations are natural or damped ?
State which kind of vibrations (free, forced or resonant) are the following:
i) A tuning fork is struck against a rubber pad and its stem is held in hand.
ii) Two large tuning forks each of frequency 512 Hz with their stems fixed on wooden boxes are placed 1 m apart on a table. When one is set into vibrations the other too is observed to emit sound.
