- n. Quickness of motion; swiftness; speed; celerity; rapidity
- n. 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.

- n. The velocity at which the mode of flow of a liquid, in a pipe or channel, is modified by the setting up of eddy-motion and the consequent interruption of the stream lines.
- n. Same as critical velocity .
- n. The velocity of a given individual wave-length of light as opposed to the group velocity of a complex beam taken as a whole.
- n. Quickness of motion; speed in movement; swiftness; rapidity; celerity: used only (or chiefly) of inanimate objects. See def. 2.
- n. .2. In physics, rate of motion; the rate at which a body changes its position in space; the rate of change of position of a point per unit of time.

In 1899 Lenard demonstrated the cause to be the emission of electrons at a certain velocity from the negatively charged body.
One of the things -- we're working on things like what we call velocity, which is the ability to turn the backlogs faster.
And it's what we call the velocity of money still has to improve.
Hamels, who said his velocity is always down this early in the season, said location was his biggest problem, along with Colorado's thin air, which robbed him of his curveball and forced him to throw a steady diet of changeups, which he hung, and fastballs, which '' were right down the middle. ''
The Earth's escape velocity is about 11 km per second.
Opus Dei weirdican Ruth Kelly was unavailable for religious comment, as she was playing with her cilice, but BBC Weather Girl Carol Kirkwood said, "We advise people not to travel, as getting a frog in the face at terminal velocity is not likely to make for a good day".
But I do think that velocity is a important factor in penetration regardless of the caliber used as long as tough quality bullets are what actually strikes the animal.
Once terminal velocity is reached, the sensation of falling diminishes.
Thus, one might deem that a particle's mass and charge are intrinsic properties, whilst its velocity is an extrinsic property, depending as it does upon the reference frame chosen.
Forget an explosives package, the kinetic energy of any hardware at orbital velocity is destructive in a collision.
