Vibration is the repeated back-and-forth motion of a particle when displaced from its equilibrium position. Due to its oscillatory property, it exhibits a periodic or repetitive motion. A periodic motion is characterized by repeatedly occurring motion at regular time intervals.

Pitch is a measure of how high or low something sounds and is related to the speed of the vibrations that produce the sound. Volume is a measure of how loud or soft something sounds and is related to the strength of the vibrations. Sound is caused by vibrations (back and forth movements. that occur very quickly)

Amplitude is a measurement of the amount of energy transferred by a wave. Amplitude on a transverse wave is typically measured as the distance between the peak or trough of the wave and the equilibrium position, or the position of the medium at rest.
