(a) Draw a graph between displacement and time for a body executing the natural vibrations.
(b) Where can a body execute the natural vibrations ?
State one condition for a body to execute the natural vibrations.
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.
