Vibration is the oscillation (periodic back-and-forth motion) of an object about a static position. Example of vibration is a weight suspended from a spring.
Vibrations fall into two categories: free and forced. Free vibrations occur when the system is disturbed momentarily and then allowed to move without restraint.
