Measuring Vibration with Accelerometers
Free vibration occurs when an object or structure is displaced or impacted and then allowed to oscillate naturally. For example, when you strike a tuning fork, it rings and then the sound eventually diminishes. Natural frequency often refers to the frequency at which a structure "wants" to oscillate after an impact or displacement.
