State two differences between the forced and resonant vibrations.

Open in App

Solution

Forced Vibrations Resonant Vibrations
The vibrations of a body under an external periodic force of frequency different from the natural frequency of the body are called forced vibrations.
The amplitude of vibration is small.
The vibrations of a body under an external periodic force of frequency exactly equal to the natural frequency of the body, are called resonant vibrations.
The amplitude of vibration is very large.
