Velocity   Listen
noun
Velocity  n.  (pl. velocities)  
1.
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. Note: In such phrases, velocity is more generally used than celerity. We apply celerity to animals; as, a horse or an ostrich runs with celerity; but bodies moving in the air or in ethereal space move with greater or less velocity, not celerity. This usage is arbitrary, and perhaps not universal.
2.
(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.
Angular velocity. See under Angular.
Initial velocity, the velocity of a moving body at starting; especially, the velocity of a projectile as it leaves the mouth of a firearm from which it is discharged.
Relative velocity, the velocity with which a body approaches or recedes from another body, whether both are moving or only one.
Uniform velocity, velocity in which the same number of units of space are described in each successive unit of time.
Variable velocity, velocity in which the space described varies from instant to instant, either increasing or decreasing; in the former case called accelerated velocity, in the latter, retarded velocity; the acceleration or retardation itself being also either uniform or variable.
Virtual velocity. See under Virtual. Note: In variable velocity, the velocity, strictly, at any given instant, is the rate of motion at that instant, and is expressed by the units of space, which, if the velocity at that instant were continued uniform during a unit of time, would be described in the unit of time; thus, the velocity of a falling body at a given instant is the number of feet which, if the motion which the body has at that instant were continued uniformly for one second, it would pass through in the second. The scientific sense of velocity differs from the popular sense in being applied to all rates of motion, however slow, while the latter implies more or less rapidity or quickness of motion.
Synonyms: Swiftness; celerity; rapidity; fleetness; speed.

"Velocity" Quotes from Famous Books



... enabled them—and it was a consideration of primary importance—to traverse the air at enormous speeds, and so run no risks of unanticipated weather. The briefest journey performed, that from London to Paris, took about three-quarters of an hour, but the velocity attained was not high; the leap to New York occupied about two hours, and by timing oneself carefully at the intermediate stations it was possible in quiet weather to go around the world ...

... among the college Faculty a disposition to undervalue the physical sciences." Dr. James F. Dana, the predecessor of Professor Hale, writing of the college in reference to physical science, used the following remarkable expression: "It was anchored in the stream, and served only to show its velocity." When Professor Hale was engaged, his duties comprised a course of daily lectures to the medical class through the lecture term, to which lectures the members of the Senior and Junior classes were to be admitted; and instruction to the Junior ...

... course round the ring FROM WEST TO EAST, crossing and recrossing the middle of the annular circle. "Some stars will depart more, others less, from either side of the circumference of equilibrium, according to the places in which they are situated, and according to the direction and the velocity with which they are put in motion. Our sun is probably one of those which depart furthest from it, and descend furthest into the empty space within the ring." {6} According to this view, a time may come when we shall be much more in the thick of ...

... roughly illustrated by radii drawn to the circumference of a very eccentric ellipse from its northern focus. Wherever the waste of the entire island may descend, it is met by a seaward tide twice in the twenty-four hours. On the East River side the velocity of this tide in the narrow passages is rather that of a mill-stream than of the entrance to a sound. Though less apparent, owing to its area, the tide and current of the Hudson are practically as irresistible. The two branches of the city-sewage, ...

... shore, and I was in attendance as an acolyte. But our earliest winter in South Devon was darkened for us both by disappointments, the cause of which lay, at the time, far out of my reach. In the spirit of my Father were then running, with furious velocity, two hostile streams of influence. I was standing, just now, thinking of these things, where the Cascine ends in the wooded point which is carved out sharply by the lion- coloured swirl of the Arno on the one side and by the pure flow of the Mugnone on the other. The rivers meet, and ...

We have violent thunder storms and sometimes for a few minutes in advance of a storm we have a wind velocity of sixty or seventy miles an hour. If at the time the leaves happen to be wet the battering power of a seventy-mile wind is so tremendous that it will break out almost any form of graft. But my splice grafts ...

In a similar manner, when a savage sees a mark struck by a bullet, it may be some time before he is able at all to understand how it is effected; for the fact of a body being invisible from its velocity would perhaps be to him an idea totally inconceivable. Moreover, the extreme force of a bullet, that penetrates a hard substance without tearing it, may convince the savage that it has no force at all. Certainly I believe that many savages of ...

The question under discussion was whether the measure of vis viva is equal, as the Cartesians thought, to the product of the mass into the velocity, or, according to the Leibnitzians, to the product of the mass into the square of the velocity.

Without a moment's warning I was dragged suddenly into the heart of one. I spun round for a minute or two with such velocity that I almost lost my senses, and then fell suddenly, left wing foremost, down the vacuum funnel in the centre.

He then points out that, "to fill all space with a new medium, whenever any new phenomenon is to be explained, is by no means philosophical"; and further adds, that "If it should be found that the velocity of propagation of electro-magnetic disturbances is the same as the velocity of light, and this not only in air, but in other transparent media, we shall have strong reasons for believing that light is an electro-magnetic phenomena." In the wave theory of light we have ...

... tremendous rush, as if an immense wave of the sea had suddenly rolled up the stream, and, finding itself confined on either side, extended across, like a high bank of water, curling and breaking as it went, and, from the frightful velocity with which it passes up, carrying all before it. There are, however, certain bends of the river where the bore does not break across: it was now our business to look out for and gain these spots between the times of its activity. The natives hold them ...

It has been widely believed that the velocity of light is the limiting velocity, and many of our leading authorities hold this view—but it cannot be proved, and is by no means universally held. In this connection, it would appear that J. J. Thompson, in "Beyond the Electron" shows, to his own satisfaction ...

... Lake, as we shall call the expansion, a blinding snowstorm was raging, with a strong head wind. Several rapids were run though it was extremely dangerous work, for at times we could scarcely see a dozen yards ahead. At midday the snow ceased, but the wind increased in velocity until finally we found it quite out of the question to paddle against it, and were forced to pitch camp on the shores of a small expansion and under the lee of a hill. For two days the gale blew unceasingly and held us prisoners in ...

The phenomenon was of daily occurrence until ...

... Precisely how it happened I could not possibly say, it occurred so suddenly, and moreover I only saw the last part of it; but I imagine that the lad must have lost, or inadvertently released, his hold upon the side of the companion at the critical moment when the velocity of the ship's roll was at its highest. Be that as it may, Julius no sooner stepped out on deck than he went with a run straight to the lee rail of the poop, fetched up against it with a force that must have knocked the breath out of him, and then— although the rail ...

... the attitude of the statisticians, who showed no enthusiastic confidence in their own figures. They should have reached certainty, but they talked like other men who knew less. The method did not result faith. Indeed, every increase of mass — of volume and velocity — seemed to bring in new elements, and, at last, a scholar, fresh in arithmetic and ignorant of algebra, fell into a superstitious terror of complexity as the sink of facts. Nothing came out as it should. In principle, according to figures, any one could ...

The other, hearing the earthly thunder and Jacky's exulting whoop, gave a sudden whirl with his long wing and shot up into the air at an angle and made off with great velocity; but the second barrel followed him as he turned and followed him as he flew down the wind. Bang! out flew two handfuls of dusky feathers, and glutton No. 2 died in the air, and its carcass and expanded wings went whirling like a sheet of paper and fell on the top of a bush at the ...

If we suppose the space given to six platforms of three feet wide and one (the most rapid) of six feet, and if we suppose each platform to be going four miles an hour faster than its slower fellow (a velocity the Paris experiment has shown to be perfectly comfortable and safe), we should have the upper platform running round the circle at a pace of twenty-eight miles an hour. If, further, we adopt an ingenious suggestion of Professor Perry's, and imagine ...

For sound travels at the rate of 1142 feet in a second of time, and the velocity of light through such small distances is not to be estimated. In these circumstances a person will be safer by lying down on the ground, than erect, and still safer if within a few feet of his horse; which being then a more elevated ...

The first effect of the levees is to raise the surface; but this, by inducing greater velocity of flow, inevitably causes an enlargement of section, and if this enlargement is prevented from being made at the expense of the banks, the bottom must give way and the form of the waterway be so improved as to admit this flow with less ...

It seems to me, also, that the velocity of light through space is the deus ex machina in Einstein's physics.

Too strong a current tends to raise the pitch, a result which can be prevented only by extra tension of the vocal cords, which, of course, entails unnecessary strain. Again, the air may be sent up with such velocity that some of it leaks through before the glottis has time to intercept it; or with such violence as to force the lips of the chink a little too far apart. In either case so much motive power is thrown away and to that extent the brilliancy and fullness of the tone are lost. The coup de ...
