what is natural vibration, forced vibration, and resonance?

Open in App

Solution

Natural vibration:-
If we apply a small force on an object and remove it.
It starts vibrating with a particular frequency continuously.Then it is called natural vibration.
Forced vibration:-
When an object is under the periodic varying force, then the object starts vibrating with the frequency of applied force. Then it is called forced vibration.
Resonance:-
If the frequency of forced vibration is equal to the natural frequency. It is called resonance.
This time amplitude of the vibration is maximum.

When a body vibrates under a periodic force, the vibrations of the body are :

(a) natural vibrations (b) damped vibrations

Q. Assertion :Resonance is a special case of forced vibration in which the natural frequency of vibration of the body is the same as the impressed frequency of external periodic force and the amplitude of forced vibration is maximum. Reason: The amplitude of forced vibrations of a body increases with an increase in the frequency of the externally impressed periodic force.

“Resonance is a special case of forced vibration”. This is because
