ve·loc·i·ty

 (və-lŏs′ĭ-tē)
n. pl. ve·loc·i·ties
1. Rapidity or speed of motion; swiftness.
2. Physics A vector quantity whose magnitude is a body's speed and whose direction is the body's direction of motion.
3.
a. The rate of speed of action or occurrence.
b. The rate at which money changes hands in an economy.

[Middle English velocite, from Old French, from Latin vēlōcitās, from vēlōx, vēlōc-, fast; see weg- in Indo-European roots.]

velocity

(vɪˈlɒsɪtɪ)
n, pl -ties
1. speed of motion, action, or operation; rapidity; swiftness
2. (Units) physics a measure of the rate of motion of a body expressed as the rate of change of its position in a particular direction with time. It is measured in metres per second, miles per hour, etc. Symbol: u, v or w
3. physics (not in technical usage) another word for speed3
[C16: from Latin vēlōcitās, from vēlōx swift; related to volāre to fly]

ve•loc•i•ty

(vəˈlɒs ɪ ti)

2. Mech. the time rate of change of position of a body in a specified direction.
[1540–50; < Latin vēlōcitās speed. See velocipede, -ty2]
syn: See speed.

ve·loc·i·ty

(və-lŏs′ĭ-tē)
The rate at which an object moves in a specified direction.
Usage We normally think of velocity as the speed at which an object is traveling. But in physics, velocity and speed are not the same. Like speed, velocity refers to the rate at which an object is moving—the distance per unit of time. But velocity in physics also includes the direction in which the object is moving, whereas direction has no bearing on an object's speed. For example, if two cars were driving at a rate of 50 miles per hour, and both headed due north, you could rightly say that they were both traveling at the same speed and at the same velocity. But if one of the cars were to turn west at a certain point, continuing at the same rate of 50 miles per hour, you could only say that they were traveling at the same speed, not at the same velocity. Similarly, traveling around a curve, a car may maintain the same speed throughout, but its velocity will be constantly changing. This change in velocity over time is called acceleration.

velocity

Rate of motion in a particular direction.
