Definition of Natural Frequency
Quick fact
A pendulum clock keeps time by vibrating at its natural frequency, which is determined by its length and gravity.
Why this is interesting
Have you ever noticed a swing moving at its own pace without anyone pushing it? That's an example of natural frequency in action.

Understanding Definition of Natural Frequency
Natural frequency is the rate at which a system naturally vibrates when disturbed. Imagine plucking a guitar string—it moves back and forth at a specific speed without any outside push. That's its natural frequency. It depends on how stiff or flexible the system is, like how tight a spring is or how heavy an object is.
A deeper explanation
Natural frequency arises from the internal properties of a system, such as mass and stiffness. When energy is applied to a system, it oscillates at this intrinsic rate. This behavior is fundamental in engineering and physics because understanding natural frequency helps prevent dangerous vibrations and design systems that work efficiently with or against these inherent rhythms.
