Oscillation
A periodic back-and-forth motion or variation around an equilibrium point, fundamental to physics, nature, and numerous scientific phenomena.
Oscillation
Oscillation describes the repetitive variation of a quantity or state around a central value or position. This fundamental phenomenon appears throughout nature and forms the basis for many scientific principles and technological applications.
Physical Principles
At its core, oscillation requires:
- A equilibrium state
- A restoring force that pulls the system back toward equilibrium
- An energy source or initial displacement
- A medium or system that can store both potential energy and kinetic energy
