AI overview
Vibration is the rapid back-and-forth movement of objects or materials, like the surface of a drum oscillating or a car's suspension responding to bumps in the road. Understanding and controlling vibrations matters because engineers in fields like automotive and acoustics design systems to manage unwanted vibrations and improve how machines and vehicles perform.

In mechanics, vibration () is oscillatory motion about an equilibrium point. Vibration may be deterministic if the oscillations can be characterised precisely (e.g. the periodic motion of a pendulum), or random if the oscillations can only be analysed statistically (e.g. the movement of a tire on a gravel road).
