Velocity (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..

Lern More About Velocity

Deaden :: Deaden (a.) To lessen the velocity or momentum of; to retard; as, to deaden a ship's headway..
Libration Point :: Libration point (n.) any one of five points in the plane of a system of two large astronomical bodies orbiting each other, as the Earth-moon system, where the gravitational pull of the two bodies on an object are approximately equal, and in opposite directions. A solid object moving in the same velocity and direction as such a libration point will remain in gravitational equilibrium with the two bodies of the system and not fall toward either body..
Dart :: Dart (v. i.) To start and run with velocity; to shoot rapidly along; as, the deer darted from the thicket..
Carronade :: Carronade (n.) A kind of short cannon, formerly in use, designed to throw a large projectile with small velocity, used for the purpose of breaking or smashing in, rather than piercing, the object aimed at, as the side of a ship. It has no trunnions, but is supported on its carriage by a bolt passing through a loop on its under side..
Instantaneous :: Instantaneous (a.) At or during a given instant; as, instantaneous acceleration, velocity, etc..
Nephoscope :: Nephoscope (n.) An instrument for observing the clouds and their velocity.
Velocity :: Velocity (n.) 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..
Rotation :: Rotation (a.) Pertaining to, or resulting from, rotation; of the nature of, or characterized by, rotation; as, rotational velocity..
Hemadromometry :: Hemadromometry (n.) The act of measuring the velocity with which the blood circulates in the arteries; haemotachometry.
Swift :: Swift (v. i.) Moving a great distance in a short time; moving with celerity or velocity; fleet; rapid; quick; speedy; prompt.
Rhysimeter :: Rhysimeter (n.) An instrument, acting on the principle of Pitot's tube, for measuring the velocity of a fluid current, the speed of a ship, etc..
Backlash :: Backlash (n.) The distance through which one part of connected machinery, as a wheel, piston, or screw, can be moved without moving the connected parts, resulting from looseness in fitting or from wear; also, the jarring or reflex motion caused in badly fitting machinery by irregularities in velocity or a reverse of motion..
Anemometer :: Anemometer (n.) An instrument for measuring the force or velocity of the wind; a wind gauge.
Hydrometer :: Hydrometer (n.) An instrument, variously constructed, used for measuring the velocity or discharge of water, as in rivers, from reservoirs, etc., and called by various specific names according to its construction or use, as tachometer, rheometer, hydrometer, pendulum, etc.; a current gauge..
Chronoscope :: Chronoscope (n.) An instrument for measuring minute intervals of time; used in determining the velocity of projectiles, the duration of short-lived luminous phenomena, etc..
Hydrometry :: Hydrometry (n.) The art or operation of measuring the velocity or discharge of running water, as in rivers, etc..
Fleet :: Fleet (v. i.) Swift in motion; moving with velocity; light and quick in going from place to place; nimble.
Swiftness :: Swiftly (adv.) In a swift manner; with quick motion or velocity; fleetly.
Anemometry :: Anemometry (n.) The act or process of ascertaining the force or velocity of the wind.
Fluxion :: Fluxion (n.) A method of analysis developed by Newton, and based on the conception of all magnitudes as generated by motion, and involving in their changes the notion of velocity or rate of change. Its results are the same as those of the differential and integral calculus, from which it differs little except in notation and logical method..
