Question

Explain forced oscillations and resonance.

Answer 1

Answer:

periodic force driving a harmonic oscillatorat its natural frequency produces resonance. The system is said to resonate. The less damping a system has, the higher the amplitude of the forced oscillations nearresonance. The more damping a system has, the broader response it has to varying driving frequencies.Oscillations produced by an external periodic drivingforce (with a frequency that's not the natural frequency) are called forced oscillations. There is an increase in the amplitude of oscillations when the driving force is close to natural frequency of the system.
