What Is the Difference Between Vibration and Oscillation?

Click For Summary
SUMMARY

The discussion clarifies that oscillation refers to a periodic fluctuation of a variable, such as a pendulum swinging back and forth, while vibration specifically denotes mechanical oscillation involving the motion of particles in an elastic medium. Oscillation applies broadly to various periodic movements, whereas vibration is often limited to mechanical systems. The distinction is subtle, with many experts noting that the terms are frequently used interchangeably without significant differentiation.

PREREQUISITES
  • Understanding of basic physics concepts, particularly motion and forces

What is the difference between vibration and oscillation?
 
Physics news on Phys.org
Oscillation refers to a periodic fluctuation of a variable, or a variation above and below a mean value, e.g. a pendulum, a periodic flow, etc, and so oscillation applies generically.

To oscillate means to swing backward and forward like a pendulum or swing, or move or travel back and forth between two points, such as a maximum and minimum.

Vibration generally refer to a mechanical oscillation, i.e. "a periodic motion of the particles of an elastic body or medium in alternately opposite directions from the position of equilibrium when that equilibrium has been disturbed (as when a stretched cord produces musical tones or molecules in the air transmit sounds to the ear)." Ref: Merriam Webster Dictionary
 
They are practically the same and I've never heard of a meaningful distinction between them. According to a quick wiki search, sometimes vibration is restricted to refer only to mechanical systems (i.e. a spring and not a beam of light).
