Vibration is a movement of molecules, which typically involves oscillation about an equilibrium point, and is distinct from its motion and velocity.

Amplitude describes the degree of vibration noted on the object. More movement means more criticality of the object condition. Velocity or speed shall be measured in a specific direction in terms of peak value or rms (root-mean-square) value. Its unit is in/s or mm/s.

Frequency: a machine may oscillate quickly or slowly depending on the vibration. The rate of machine-part oscillation is called vibration frequency. Number of oscillation cycles per second is defined as the frequency, e.g. 3 cycles per second (Hertz) or 3 cycles per minute.

Spectrum: It is combination of the frequency of component vibration and velocity amplitude measured at that time.
