acceleratory

Causing faster motion

Acceleratory means causing or relating to acceleration—an increase in speed or rate.

The word appears mainly in technical contexts: acceleratory forces acting on the vehicle, the acceleratory phase of growth.

It functions as the adjective form where "accelerating" might sound awkward, though it remains relatively uncommon outside scientific writing.
