ACCELERATION
n.The act of increasing velocity or progress; the state of being quickened in motion or action. Accelerated motion in mechanics and physics, is that which continually receives accessions of velocity; as, a falling body moves towards the earth with an acceleration of velocity. It is the opposite of retardation. Acceleration of the moon, is the increase of the moon's mean motion from the sun, compared with the diurnal motion of the earth; the moon moving with more velocity now than in ancient times - a discovery made by Dr. Halley.
The diurnal acceleration of the fixed stars, is the time by which they anticipate the mean diurnal revolution of the sun, which is nearly three minutes, fifty-six seconds.

Ac *cel `er *a "tion, n. Etym: [L. acceleratio: cf. F. accélération.]
Defn: 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. I. Taylor. (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 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.
