1. velocity love

## Definitions

### American Heritage® Dictionary of the English Language, Fourth Edition

1. n. Rapidity or speed of motion; swiftness.
2. n. Physics A vector quantity whose magnitude is a body's speed and whose direction is the body's direction of motion.
3. n. The rate of speed of action or occurrence.
4. n. The rate at which money changes hands in an economy.

### Century Dictionary and Cyclopedia

1. 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.
2. n. Same as critical velocity .
3. 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.
4. n. Quickness of motion; speed in movement; swiftness; rapidity; celerity: used only (or chiefly) of inanimate objects. See def. 2.
5. 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. The velocity of a body is uniform when it passes through equal spaces in equal times, and it is variable when the spaces passed through in equal times are unequal. The velocity of a body is accelerated when it passes constantly through a greater space in equal successive portions of time, as is the case with falling bodies under the action of gravity, and it is retarded when a less space is passed through in each successive portion of time. When the motion of a body is uniform its velocity is measured by the space described by it in a unit of time, as one second. If the motion of the body is not uniform its velocity is measured by the space which it would describe uniformly in a given time if the motion became and continued uniform from that instant of time.
6. n. In music, decided rapidity of tempo or pace, particularly in a bravura passage.

### Wiktionary

1. n. physics A vector quantity that denotes the rate of change of position with respect to time, or a speed with the directional component.
2. n. Rapidity of motion.
3. n. The rate of occurrence.
4. n. economics The number of times that an average unit of currency is spent during a specific period of time.

### GNU Webster's 1913

1. n. Quickness of motion; swiftness; speed; celerity; rapidity.
2. n. (Mech.) 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.

1. n. distance travelled per unit time
