Question

Explain what is mean by resonance and give two examples where I occurs.

Answer 1

Answer:

In mechanical systems, resonance is a phenomenon that only occurs when the frequency at which a force is periodically applied is equal or nearly equal to one of the natural frequencies of the system on which it acts.

If that frequency happens to match the resonant frequency of the object it's hitting, then you'll get what's called resonance. Resonance occurs when the amplitude of an object's oscillations are increased by the matching vibrations of another object.
