sustained oscillation
sustained oscillation means oscillation in which forces outside the system, but controlled by the system, maintain a periodic oscillation of the system at a period or frequency that is nearly the natural period of the system.
Resonance oscillation
resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at a specific preferential frequency. Increase of amplitude as damping decreases and frequency approachesresonant frequency of a driven damped simple harmonic oscillator.
