#### Question

Distinguish between forced vibrations and resonance.

#### Solution

 Sr.No. Forced vibrations Resonance 1 It is produced by an external periodic force of any frequency. It is produced by an external periodic forcewhose frequency is equal to the naturalfrequency of the body 2 The frequency of vibrations isdifferent from the natural frequency of the body The frequency of vibrations is sa me as the natural frequency of the body. 3 The amplitude of vibration is small. The amplitude of vibration is very large. 4 Vibrations stop as soon as theexternal force is removed. Vibrations continue for some time even after the external force is removed 5 Faint sound is produced. Loud sound is produced.
