Answer
(i) The periodic vibrations of constant amplitude and frequency of a body in the absence of any external force on it, are called free vibrations.
(ii) The amplitude of a vibrating body continuously decrease during damped vibrations. It is due to loss of energy against the damping forces such as air, friction etc.
