n. Rapidity of motion.

n. The rate of occurrence.

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

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.

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

n. distance travelled per unit time
