Question

Define resonance. State the forces involved here. ​

Answer 1

Answer:

Resonance

It is a special case of forced vibrations when the natural frequency of the vibrating body is exactly equal to the frequency of the external periodic force applied on the body.

Such vibrations are called resonant vibrations.

The bodies which possess such vibrations are called resonating bodies.

The forces involved here are - Restoring force, resisting force and an external periodic force.
