eltolódáson

Eltolódáson is the locative form of the Hungarian noun eltolódás, which denotes displacement, offset, or shift. The term is used in various disciplines to describe a change of position or a context in which shifting occurs, such as időeltolódás (time offset) or helyzeti eltolódás (spatial displacement). The word comes from tolódik, meaning to move or shift, with the nominal suffix -ás and the locative ending -on/-en/-ön.

In mathematics and geometry, eltolódás commonly refers to a translation, a rigid motion that moves every point of a figure by the same vector without rotation or scaling. It is a simple type of geometric transformation used to reposition objects while preserving shape and size.

In physics and everyday language, eltolódás often means displacement: the change in position of an object from an initial to a final point. The concept appears in formulas as a displacement vector, and it is related to velocity as its time derivative. The broader phrase időseltolódás or időeltolódás denotes a time shift or time lag between events or signals, while fáziseltolódás refers to a phase shift in oscillatory phenomena.

In statistics or data analysis, eltolódás can describe a drift or bias in measurements over time, indicating a systematic shift of the data from a reference. Eltolódás thus serves as a general umbrella term for different notions of movement, shift, or offset across disciplines.
