An oscillation is a human-made concept designating the category of phenomena in which a quantity varies periodically around a central equilibrium value. Its parameters: (1) a measurable state that returns repeatedly to a reference point, (2) a characteristic frequency or period governing the repetition rate, (3) a distinction between free oscillation (self-sustained, e.g. pendulum) and driven oscillation (externally forced, e.g. alternating current). The persistence mechanism is mathematical formalism through differential equations, engineering standards, and pedagogical transmission across the physical sciences.

Definition
Why it is in scope
A human-made concept: the mathematical and physical category of periodic variation around a central equilibrium value. Built to persist through physics, engineering, mathematics, and signal processing as a foundational model for understanding waves, vibration, and alternating phenomena.

Pre-test which-came-first: oscillation (back-and-forth motion as a concept) existed before resonance (specific amplification at natural frequency). The broader concept of oscillatory motion fed into the later refinement of resonance as a distinct concept. Law 7 satisfied.

Remove oscillation (the concept of back-and-forth motion) and resonance (amplification at natural frequency) stops operating as a concept — it cannot be understood without its oscillatory foundation. This is a present-tense functional dependency (Law 8), distinct from the historical DERIVED_FROM Seth filed. Both can be true: resonance historically derives from oscillation AND depends on it operationally.

A wave IS a specific kind of oscillation — namely, a propagating oscillation where the disturbance moves through a medium or field. Per Law 9: specific→general. A competent speaker calls a wave 'an oscillation' qualified by propagation. Pinned to the physics sense: wave as a propagating oscillatory disturbance.

Phase is the concept of position within a cycle of a periodic phenomenon. Remove oscillation and phase cannot operate — phase is specifically defined as a position in a cycle, and cycles are the domain of oscillation. This is a genuine operational dependency, not a meta-level sayability claim.

Ringing is a specific kind of oscillation — sustained oscillation after a transient. A competent speaker would call ringing 'a type of oscillation.' Per Law 9, this is INSTANCE_OF, not DEPENDS_ON: it's about kind-of membership, not operational dependency.

Ringing is a damped oscillatory phenomenon — the oscillatory overshoot and decay that follows a step input or impulse. Remove the concept of oscillation and ringing as a concept ceases to operate: ringing IS oscillation with damping. The removal test passes at the object level.
