उत्तर
When an oscillatory system is made to oscillate under the action of an externally applied periodic force, it is said to execute forced vibrations. In this case the external frequency may or may not be equal to the natural frequency of the body.
In case of resonance, the externally applied periodic force has the same frequency as the natural frequency of oscillation of the given oscillatory system.
