Quickness of motion; swiftness; speed; celerity; rapidity; as, the velocity of wind; the velocity of a planet or comet in its orbit or course; the velocity of a cannon ball; the velocity of light.
Rate of motion; the relation of motion to time, measured by the number of units of space passed over by a moving body or point in a unit of time, usually the number of feet passed over in a second. See the Note under Speed.
I like physics. I think it is the best science out of all three of them, because generally it's more useful. You learn about speed and velocity and time, and that's all clever stuff. Tom Felton
I am sensible of the velocity of the moments, and entering that part of my head alert to the motion of the world I am aware that life was never perfect, never absolute. This bestows contentment, even a fearlessness. Harold Brodkey
Market leadership can translate directly to higher revenue, higher profitability, greater capital velocity, and correspondingly stronger returns on invested capital. Jeff Bezos
Whenever the work is itself light, it becomes necessary, in order to economize time, to increase the velocity. Charles Babbage
The proportion between the velocity with which men or animals move, and the weights they carry, is a matter of considerable importance, particularly in military affairs. Charles Babbage
