Lern More About Velocity

Speed :: Speed (n.) The act or state of moving swiftly; swiftness; velocity; rapidly; rate of motion; dispatch; as, the speed a horse or a vessel..
Translation :: Translation (n.) Motion in which all the points of the moving body have at any instant the same velocity and direction of motion; -- opposed to rotation.
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..
Momentum :: Momentum (n.) The quantity of motion in a moving body, being always proportioned to the quantity of matter multiplied into the velocity; impetus..
Hodograph :: Hodograph (n.) A curve described by the moving extremity of a line the other end of which is fixed, this line being constantly parallel to the direction of motion of, and having its length constantly proportional to the velocity of, a point moving in any path; -used in investigations respecting central forces..
Rheometer :: Rheometer (n.) An instrument for measuring the velocity of the blood current in the arteries.
Fleetness :: Fleetness (n.) Swiftness; rapidity; velocity; celerity; speed; as, the fleetness of a horse or of time..
Myograph :: Myograph (n.) An instrument for determining and recording the different phases, as the intensity, velocity, etc., of a muscular contraction..
Calculated :: Calculated (p. p. & a.) Worked out by calculation; as calculated tables for computing interest; ascertained or conjectured as a result of calculation; as, the calculated place of a planet; the calculated velocity of a cannon ball..
Acceleration :: Acceleration (n.) The act of accelerating, or the state of being accelerated; increase of motion or action; as, a falling body moves toward the earth with an acceleration of velocity; -- opposed to retardation..
Hemadromometer :: Hemadromometer (n.) An instrument for measuring the velocity with which the blood moves in the arteries.
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..
Convoy :: Convoy (n.) A drag or brake applied to the wheels of a carriage, to check their velocity in going down a hill..
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..
Hydrodynamometer :: Hydrodynamometer (n.) An instrument to measure the velocity of a liquid current by the force of its impact.
Hydrometry :: Hydrometry (n.) The art or operation of measuring the velocity or discharge of running water, as in rivers, etc..

Anemometry :: Anemometry (n.) The act or process of ascertaining the force or velocity of the wind.
Fleet :: Fleet (v. i.) Swift in motion; moving with velocity; light and quick in going from place to place; nimble.
