Difference between forced vibrations and resonance.

1)When an external force causes an object to begin vibrating, this type of vibration is known as forced vibration. 2)Resonance is the state in which a forced vibration's frequency equals its natural frequency.3)The difference between forced vibration and resonance are given below
Force vibration:
1.An external periodic force of any frequency causes a force to vibrate.
2.The amplitude of vibration is very small.
Resonance:
1.An external periodic force with a frequency equal to the body's natural frequency can also cause resonance.
2.The amplitude of vibration is large.
