noun. Rapidity or speed of motion; swiftness.

noun. A vector quantity whose magnitude is a body's speed and whose direction is the body's direction of motion.

noun. undefined

noun. The rate of speed of action or occurrence.

noun. The rate at which money changes hands in an economy.

noun. Quickness of motion; speed in movement; swiftness; rapidity; celerity: used only (or chiefly) of inanimate objects. See def. 2.

noun. .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.

noun. In music, decided rapidity of tempo or pace, particularly in a bravura passage.

noun. 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.

noun. Same as critical velocity .

noun. The velocity of a given individual wave-length of light as opposed to the group velocity of a complex beam taken as a whole.

noun. Quickness of motion; swiftness; speed; celerity; rapidity

noun. 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.

noun. See under Angular.

noun. the velocity of a moving body at starting; especially, the velocity of a projectile as it leaves the mouth of a firearm from which it is discharged.

noun. the velocity with which a body approaches or recedes from another body, whether both are moving or only one.

noun. velocity in which the same number of units of space are described in each successive unit of time.

noun. velocity in which the space described varies from instant to instant, either increasing or decreasing; -- in the former case called accelerated velocity, in the latter, retarded velocity; the acceleration or retardation itself being also either uniform or variable.

noun. See under Virtual.

noun. A vector quantity that denotes the rate of change of position with respect to time, or a speed with the directional component.

noun. Rapidity of motion.

noun. The rate of occurrence.

noun. The number of times that an average unit of currency is spent during a specific period of time.

noun. distance travelled per unit time

"In 1899 Lenard demonstrated the cause to be the emission of electrons at a certain velocity from the negatively charged body."
