| acceleration | 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. <astronomy> Taylor) 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. Origin: L. Acceleratio: cf. F. Acceleration.

| acceleration phase | <cell biology, cell culture> A period of increasing growth before the log phase in a culture of microbes. After the culture is started on a medium, at first there is no growth (the lag phase) and then the microbes start to gradually grow (acceleration phase) until they reach a constant maximum rate of growth (log phase). (15 Jan 1998) |
| angular acceleration | The rate of change of angular velocity; e.g., when a centrifuge rotor is speeding up, or when there is a simultaneous change in velocity and direction, as in an aircraft in a tight spin. (05 Mar 2000) |
| radial acceleration | The centripetal acceleration of a particle or vehicle moving along a curved path at a constant velocity; e.g., turning a curve in an automobile, pulling out of a dive, or performing a loop manoeuvre in an aircraft. In aviation, acceleration varies directly with the square of the air speed and inversely with the radius of the turn (a = V2/r, where V is air speed and r is radius of turn). (05 Mar 2000) |
| linear acceleration | The rate of change of velocity without a change in direction; e.g., when the speed of an aircraft increases while flying a straight pathway. (05 Mar 2000) |
| absolute gravity | <chemistry> The value that denotes the density (specific gravity) at standard conditions (for gases, these conditions are standard atmospheric pressure at zero degrees Celsius). (06 May 1997) |
| gravity | Origin: L. Gravitas, fr. Gravis heavy; cf. F. Gravite. See Grave, Grief. 1. The state of having weight; beaviness; as, the gravity of lead. 2. Sobriety of character or demeanor. "Men of gravity and learning."< p. 648 needs proofing ##proof - especially italicized words (aso in etymologies) are not properly marked 3. Importance, significance, dignity, etc; hence, seriousness; enormity; as, the gravity of an offense. "They derive an importance from . . . The gravity of the place where they were uttered." (Burke) 4. <physics> The tendency of a mass of matter toward a center of attraction; especially, the tendency of a body toward the center of the earth; terrestrial gravitation. 5. Lowness of tone; opposed to acuteness. Center of gravity See Center. Gravity battery, See Battery. Specific gravity, the ratio of the weight of a body to the weight of an equal volume of some other body taken as the standard or unit. This standard is usually water for solids and liquids, and air for gases. Thus, 19, the specific gravity of gold, expresses the fact that, bulk for bulk, gold is nineteen times as heavy as water.

| gravity, altered | A change in, or manipulation of, gravitational force. This may be a natural or artificial effect. (12 Dec 1998) |
| gravity perception | Process whereby a bodily structure or organism (animal or plant) receives or detects a gravity stimulus. The sensing may be direct or indirect and may or may not initiate a reaction to the stimulus. (12 Dec 1998) |
| specific gravity | A measure of concentration. It is the weight of a substance, as compared (as a ratio) with that of an equal volume of water. (27 Sep 1997) |
| zero gravity | A physical state existing in space or at a time in flight when the centrifugal thrust of a parabolic glide or turn exactly counteracts the force of gravity. (05 Mar 2000) |
