$\pink{ ❐ }$Vibration, periodic back-and-forth motion of the particles of an elastic body or medium, commonly resulting when almost any physical system is displaced from its equilibrium condition and allowed to respond to the forces that tend to restore equilibrium.

$\red{ ❐ }$A vibrating motion can be oscillating, reciprocating, or periodic. ... Vibration can also be either harmonic or random. Harmonic vibration occurs when a vibration's frequency and magnitude are constant. A vibration is random when the frequency and magnitude vary with time.
