Acceleration   Listen
noun
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. "A period of social improvement, or of intellectual advancement, contains within itself a principle of acceleration."
(Astr. & Physics.)
Acceleration of the moon, the increase of the moon's mean motion in its orbit, in consequence of which its period of revolution is now shorter than in ancient times.
Acceleration of the tides and retardation of the tides. See Priming of the tides, under Priming.
Diurnal acceleration of the fixed stars, the amount by which their apparent diurnal motion exceeds that of the sun, in consequence of which they daily come to the meridian of any place about three minutes fifty-six seconds of solar time earlier than on the day preceding.
Acceleration of the planets, the increasing velocity of their motion, in proceeding from the apogee to the perigee of their orbits.

... velocity—being out of sight in a very few seconds. I did not at first know what to make of this extraordinary phenomenon; not being able to believe that my rate of ascent had, of a sudden, met with so prodigious an acceleration. But it soon occurred to me that the atmosphere was now far too rare to sustain even the feathers; that they actually fell, as they appeared to do, with great rapidity; and that I had been surprised by the united velocities of their descent and ...

... applied the same methods in the reconstruction of these roads that he had already adopted in Scotland and Wales, and the same improvement was shortly felt in the more easy passage over them of vehicles of all sorts, and in the great acceleration of the mail service. At the same time, the line along the coast from Bangor, by Conway, Abergele, St. Asaph, and Holywell, to Chester, was greatly improved. As forming the mail road from Dublin to Liverpool, it was considered of importance ...

... as strengthening exercises for the colon. This long tubular muscle is repeatedly and completely filled with water, inducing it to vigorously exercise while evacuating itself multiple times. The result is a great increase in muscle tone, acceleration of peristalsis and eventually, after several dozens of repetitions, a considerable reduction of transit time. Well-done enemas work the colon somewhat less effectively and do not improve muscle tone quite as ...

And step by step with these developments will come a very considerable acceleration of the ferry traffic of the narrow seas through such improvements as the introduction of turbine engines. So far as the high road and the longer journeys go this is the extent of ...

I kept watching the apparent distance between them shrink as I continued my trip toward Earth. Memory and a little calculating told me that my acceleration of three inches per second per second would take twenty seconds of blast to slow me to a stop. I counted them off, aloud: "Mississippi one, Mississippi two, Mississippi three," as I had been taught to measure seconds. When I got to Mississippi twenty my visual measurement said ...

... built, he paused a moment in front of the guard, who seemed to recognize him and opened the wicket without the exchange of a pass word. He then began the descent of the steep and tortuous Mountain Hill, walking briskly indeed, but with hardly a perceptible acceleration of the pace which he had held previously. It was not long before he attained the foot of the Hill, and he was about turning the very dark corner which led into Peter street, where he resided, when his step was suddenly arrested by a shrill whistle on his left. He looked around, and listened, ...

Railways and rapid steamboats enable coin and bullion to be more swiftly remitted than of old; telegraphs prevent its needless removal, and the acceleration of the mails has a like effect."

And this is the capital phenomenon of civilization. ...

The advent of a strongly-Socialist Government would mean no immediate revolutionary changes at all.

But the Austrian pressure on Italy from the Trentino seems to have forced an acceleration which the German attack on Verdun failed to extort from the Western Allies; and on 3 June a bombardment began on the whole of the Russian front from the Pripet marshes southwards to the Rumanian border. ...

But pulled together by the fine and firm fingers that seemed to guide rather than check his exuberance, he presently struck into the long, swinging pace of his kind, and kept it throughout without "break" or acceleration. Over the paved streets the light buggy rattled, and the slender shafts danced around his smooth barrel, but when they touched the level high road, horse and vehicle slipped forward through the night, a swift and noiseless phantom. Mrs. Tucker could see his graceful ...

... himself, or of Stevinus,[124] Galileo, Guldinus,[125] or Ghetaldus. He makes no allusion to the theory of equilibrium. He observes that a ball of one pound weight will fall nearly as fast through the air as a ball of two, without alluding to the theory of the acceleration of falling bodies, which had been made known by Galileo more than thirty years before. He proposes an inquiry with regard to the lever—namely, whether in a balance with arms of different length but equal weight the distance from the ...

Going through the movements of operating the complicated equipment of a spaceship, they pushed, pulled, jerked, snapped on imaginary switches, read unseen meters and gauges, and slammed around in their chairs to simulate acceleration reaction. The three cadets of the Polaris unit could no longer restrain themselves and broke into loud laughter at the antics of the aspirants. Finally, when they had landed their imaginary ship again, the Earthworms were pounded on the ...

Hosh-el-Geref was therefore not reached until the 1st of August—a day later than had been expected; but the rest had proved of such benefit to the troops that the subsequent acceleration of progress fully compensated for the delay. The column moved on again at midnight and halted at daybreak at Salmi. In the small hours of the next morning the march was resumed. The road by the Nile was found too difficult for the Maxim ...

In the railed-off sanctum in one corner of the control room a bell tinkled, a smothered whirr was heard, and Captain Bradley frowned as he studied the brief message upon the tape of the recorder—a message flashed to his desk from the operator's panel.
