Etymology First attested in 1531. From French accélération or more likely directly from Latin accelerātiō (“a hastening, acceleration”). Equivalent to accelerate + -ion.
1
The act of accelerating, or the state of being accelerated; increase of motion or action; as opposed to retardation or deceleration.
- A falling body moves toward the earth with an acceleration of velocity.
- If you hear flutter on acceleration, it is dangerous surge.2026, Mohammed Hamed Ahmed Soliman, Turbocharger Diagnostics & Performance Optimization: Boost Control, Failure Analysis, and Tuning for Modern Forced Induction Systems, Personal Lean Publictations, page 82:

- On the East and West Coast Main Lines in the 1950s/60s, for example, we saw the extinction of intermediate stations in order to create the same sort of accelerations that IRP is now promising. Back then, the priority was faster main line services, with wayside/intermediate stations paying the ultimate price.2022 January 12, Nigel Harris, “Comment: Unhappy start to 2022”, in RAIL, number 948, page 3:
2
The amount by which a speed or velocity increases (and so a scalar quantity or a vector quantity).
- The boosters produce an acceleration of 20 metres per second per second.
- A period of social improvement, or of intellectual advancement, contains within itself a principle of acceleration […]1859-1860, Isaac Taylor, Ultimate Civilisation:
