The discussion clarifies the distinctions between vibration, oscillation, simple harmonic motion, and periodic motion. Vibration refers to the motion of different parts of an object oscillating in tandem, creating waves that propagate through the body. Oscillation describes periodic motion around an equilibrium position due to forces, while simple harmonic motion is a specific type of periodic motion characterized by a sine function. Periodic motion encompasses any motion that repeats itself, but vibration can also include non-periodic and complex patterns, such as random vibration used in engineering contexts.

dauto said:Vibration is when different parts of an object oscillate in tandem forming waves that propagate through the body.
AlephZero said:If that is the definition from some reference source, fine (but it would be nice to know the source).
But I would define vibration in a more general way, as any type of motion of an object around some equilibrium position. Not necessarily periodic, and not necessarily forming anything that looks like "waves". For example "random vibration" is certainly used in engineering to describe motion that can only be described and analyzed statistically.
