This dictionary definitions page includes all the possible meanings, example usage and translations of the word Velocity.
distance travelled per unit time
A vector quantity that denotes the rate of change of position with respect to time, or a speed with the directional component.
Rapidity of motion.
The rate of occurrence.
The number of times that an average unit of currency is spent during a specific period of time.
Etymology: From velocitas, from velox.
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. 60 km/h northbound). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object is said to be undergoing an acceleration.
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
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
In kinematics, velocity is the rate of change of the position of an object, equivalent to a specification of its speed and direction of motion. Speed describes only how fast an object is moving, whereas velocity gives both how fast and in what direction the object is moving. If a car is said to travel at 60 km/h, its speed has been specified. However, if the car is said to move at 60 km/h to the north, its velocity has now been specified. To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion in a straight path. Thus, a constant velocity means motion in a straight line at a constant speed. If there is a change in speed, direction, or both, then the object is said to have a changing velocity and is undergoing an acceleration. For example, a car moving at a constant 20 kilometres per hour in a circular path has a constant speed, but does not have a constant velocity because its direction changes. Hence, the car is considered to be undergoing an acceleration. Velocity is a vector physical quantity; both magnitude and direction are required to define it. The scalar absolute value of velocity is called "speed", a quantity that is measured in metres per second when using the SI system. For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. The rate of change of velocity as a function of time is "acceleration", which describes how an object's speed and direction of travel change at each point in time. In science a "deceleration" is called a "negative acceleration", for example: −2 m/s².
Chambers 20th Century Dictionary
vē-los′i-ti, n. swiftness: speed: rate of change of position of a point per unit of time.—n. Velocim′eter, an apparatus for measuring velocity.—Initial velocity, the rate of movement of a body at starting, esp. of a projectile. [L. velocitas—velox, swift.]
The Standard Electrical Dictionary
The rate of motion of a body. It is usually expressed in distance traversed per second of time. The absolute unit is one centimeter per second or kine. The foot per second is very largely used also. The dimensions of velocity are length (L) divided by time (T) or L/T.
Dictionary of Nautical Terms
In naval architecture, designing for velocity is giving that form to a ship's body by which she will pass through the water in the quickest space of time.
Military Dictionary and Gazetteer
Is rate of motion; the relation of motion to time, measured by the number of units of space passed over by the moving body in a unit of time, usually the number of feet in a second. The velocity of a projectile, at any point of its flight, is the space in feet passed over in a second of time, with a continuous, uniform motion. Initial velocity is the velocity at the muzzle of the piece; remaining velocity is the velocity at any point of the flight; terminal velocity is the velocity with which it strikes its object; and final velocity of descent in air, is the uniform velocity with which a projectile moves, when the resistance of the air becomes equal to the accelerating force of gravity. The initial velocity of a projectile may be determined by the principles of mechanics which govern the action of the powder, the resistance of the projectile, etc., or by direct experiment.
A speed of motion.
The washing machine velocity is created at a specific speed.
