Understanding Vibration

Vibration is a movement back and forth around the equilibrium. Equilibrium here means a situation where an object is at rest if no force acting on the object. Vibration has an amplitude (the distance to the midpoint of the farthest deviation) are the same.

Type of vibration
Free vibration occurs when a mechanical system begins with the early style, and then allowed to vibrate freely. Examples of such vibration is hitting a tuning fork and let it vibrate, or a pendulum is drawn from an equilibrium state and then released.

Forced vibration occurs when the force or movement back and forth applied to mechanical systems. An example is the vibration of buildings during earthquakes.
