Defining natural frequency on the system, which consists of 2 masses and a spring, is that frequency at which the system will tend to vibrate once initiated without stimulation from an external force. All systems will eventually stop vibrating, even when stimulated at their calculated natural frequency due to inherent dampening.

This is the undamped free vibration. The motion equation is m u ″ + k u = 0. The characteristic equation is m r 2 + k = 0. Its solutions are i m k r=±. The general solution is then u(t) = C 1cos ω 0 t + C 2sin ω 0 t. Where m k ω 0 = is called the natural frequency of the system. It is the frequency at which the system tends to oscillate in the absence of any damping.
