Natural Frequency

What is natural frequency?

Hint
A vibrating object moves forward and backward from its initial position at rest. One complete vibration cycle is an object moving from one extreme position to the opposite extreme, then back again to the start location. Frequency is the number of completed cycles in one second, and is measured in hertz (Hz), which equals to one cycle per second.

All objects tend to vibrate at a particular frequency (or range of frequencies) when disturbed. Natural frequency refers to this specific default set or number an object naturally gravitates towards when strummed/hit/plucked/dropped/struck/blown etc. Keep in mind this is different from forced frequency.
