Noun
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.
Source: Webster's dictionaryI 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
Now, the velocity of wave propagation can be seen, without the aid of any mathematical analysis, to depend on the elasticity of the medium and its density; for we can see that if a medium is highly elastic the disturbance would be propagated at a great speed. Albert Abraham Michelson
From literature to ecology, from the escape velocity of galaxies to the greenhouse effect, from garbage disposal methods to traffic jams, everything is discussed in our world. But the democratic system, as if it were a given fact, untouchable by nature until the end of time, we don't discuss that. José Saramago
The way that the background fields generates mass is rather like the way in which when light passes through a transparent medium like glass or water, it gets slowed down. It no longer travels with the fundamental velocity of light c. And that's the way to think of the generation of mass. Peter Higgs
Standing at my door, I heard the discharge of a gun, and in four or five seconds of time, after the discharge, the small shot came rattling about me, one or two of which struck the house; which plainly demonstrates that the velocity of sound is greater than that of a cannon bullet. Benjamin Banneker
In turning from the smaller instruments in frequent use to the larger and more important machines, the economy arising from the increase of velocity becomes more striking. Charles Babbage
