Natural Frequency Definition. To understand resonance, we first need to understand what Natural Frequency is. The definition reads something like this: Natural Frequency is the frequency at which an object will continue to vibrate after being struck. This could not be clearer. All mechanical objects and systems have a natural frequency.
