Free vibration or natural vibration occurs when a mechanical system is set in motion with an initial input and allowed to vibrate freely. Examples of this type of vibration are pulling a child back on a swing and letting it go, or hitting a tuning fork and letting it ring.
Vibration, periodic back-and-forth motion of the particles of an elastic body or medium, commonly resulting when almost any physical system is displaced from its equilibrium condition and allowed to respond to the forces that tend to restore equilibrium. Vibrations fall into two categories: free.
Any motion that repeats itself after an interval of time is called vibration or oscillation. The swinging of a pendulum (Fig.) and the motion of a plucked string are typical examples of vibration. The theory of vibration deals with the study of the oscillatory motion of bodies and forces associated with them. Vibration Example
The meaning of VIBRATION is a periodic motion of the particles of an elastic body or medium in alternately opposite directions from the position of equilibrium when that equilibrium has been disturbed (as when a stretched cord produces musical tones or molecules in the air transmit sounds to the ear).
A vibration is a periodic back and forth motion that remains fixed in one location. Examples of vibrations include a swing moving back and forth (like a pendulum) or a mass bobbing up and down on a spring.
Wiggles, vibrations, and oscillations are an inseparable part of nature. A vibrating object is repeating its motion over and over again, often in a periodic manner. Given a disturbance from its usual resting or equilibrium position, an object begins to oscillate back and forth.

If you take any system and disturb it from a stable equilibrium, the resultant motion will be waves and vibrations. Think of a guitar string—pluck the string, and it vibrates. The sound waves generated make their way to our ears, and we hear the string’s sound. Our eyes see what’s …. Show more.
Up to now in the course considerable emphasis has been placed on finding equations of motion of mechanical systems. The study of vibration will emphasize the analysis of the solution of the equations of motion of a particularly important class of dynamics problems: the vibration of machines.
And so we're going to talk about vibration, about making vibration, about suppressing vibration, about isolating sensitive instruments from the vibration of the floor, things like that.
