What is vibration?

Explanation:
Vibration is a repetitive back-and-forth motion of an object around an equilibrium position. This back-and-forth movement is what drives sound: when an object vibrates, it pushes and pulls on the surrounding air, creating pressure waves that travel to our ears. The rate of that motion (frequency) determines pitch, how strong the motion (amplitude) relates to loudness, and the specific pattern of the motion (the waveform) shapes the sound’s timbre. It’s not the speed of sound itself, not a silent pause, and not a psychological state—those describe different ideas.
