When a system with a natural vibrating FREQUENCY is stimulated by an outside force of the same frequency, the system can be set in a motion called VIBRATION. As the frequency of the stimulus closely approaches that of the system, OSCILLATION occurs, which reaches a maximum AMPLITUDE at the natural resonant frequency.
Any quantity or body is in a state of oscillation when its value or motion is continually changing so that it passes through maximum and minimum values or positions. When a system, body or quantity is set in PERIODIC motion or vibration, it is said to be in oscillation.
