WebResonance is the relatively large selective response of an object or a system to an external oscillatory force that causes it to vibrate in step or phase. First, acoustical systems like musical instruments and the human voice were studied for resonance. A measure of stability is the likelihood that an object will collapse when pushed or moved.
