Vibrated

Vibrated is the past tense of the verb vibrate, meaning to move or cause to move rapidly back and forth or to oscillate about an equilibrium. It can describe the motion of an object or indicate that an object has been subjected to vibrations produced by another source.

In physics, a vibration is a periodic motion about an equilibrium position. Key characteristics include frequency (how many cycles occur per unit time), amplitude (the maximum displacement from equilibrium), and phase (the alignment of the motion in time). Damping reduces the amplitude over time, and resonance occurs when a system is driven near its natural frequency, potentially amplifying the vibrations.

Applications of vibration are widespread. In engineering, vibration testing subjects components and structures to controlled oscillations to assess durability and performance. In construction, vibrating equipment helps compact concrete to remove air pockets and improve strength. In music and acoustics, strings, membranes, and air columns vibrate to produce sound; objects described as vibrated may have been excited by a performer's touch, a bow, or a mechanical actuator. In measurement and sensing, accelerometers detect vibrations, and seismographs monitor ground motion from earthquakes and other sources.

Etymology traces vibrate to Latin vibrāre, meaning to brandish or shake. The term vibrated is commonly used across science, engineering, and everyday language to denote that oscillatory motion has occurred or has been induced.
