History and Etymology for velocity

Middle English velocite, borrowed from Anglo-French & Latin; Anglo-French veloceté, borrowed from Latin vēlōcitāt-, vēlōcitās, from vēlōc-, vēlōx "swift, rapid" (of uncertain origin) + -itāt-, -itās -ity

Note: If going back to earlier *ueg-s-l-o-, perhaps a derivative from the base of vegēre "to give vigor to, enliven" (see vegetate) or vehere "to convey" (Indo-European *u̯eǵh-; see vehicle), assimilated to the -ōk- of ātrōx, ferōx (see atrocious, ferocious). Alternatively, a derivative *uē-lo-, from the Indo-European base *h2u̯eh1- "blow" (hence, "windlike"; see wind entry 1) has been suggested.
