Forced Oscillations : When a body oscillates with the help of an external periodic force with a frequency different from the natural frequency of the body, its oscillations called forced oscillations.
Resonant Oscillations: When a body oscillates with its own natural frequency v„ with the help of an external periodic force whose frequency v is equal to the natural frequency of the body, the oscillations of the body are called resonant oscillations
