| gravireceptors | Highly specialised receptor organs and nerve endings in the inner ear, joints, tendons, and muscles that give the brain information about body position, equilibrium, direction of gravitational forces, and the sensation of "down" or "up." Origin: L. Gravis, heavy, + receptor (05 Mar 2000) |

| gravitate | To obey the law of gravitation; to exert a force Or pressure, or tend to move, under the influence of gravitation; to tend in any direction or toward any object. "Why does this apple fall to the ground? Because all bodies gravitate toward each other." (Sir W. Hamilton) "Politicians who naturally gravitate towards the stronger party." (Macaulay) Origin: Cf. F. Graviter. See Gravity. Source: Websters Dictionary (01 Mar 1998) |
| gravitation | Acceleration produced by the mutual attraction of two masses, and of magnitude inversely proportional to the square of the distance between the two centres of mass. It is also the force imparted by the earth, moon, or a planet to an object near its surface. (12 Dec 1998) |
| gravitation abscess | An abscess that breaks down tissue barriers to enter adjacent areas. Synonym: gravitation abscess, hypostatic abscess, migrating abscess, wandering abscess. (05 Mar 2000) |
| gravitational | <physics> Of or pertaining to the force of gravity; as, gravitational units. Source: Websters Dictionary (01 Mar 1998) |
| gravitational force | <physics> Force which attracts two bodies together based on the product of their masses and the reciprocal of the square of their distances. Gravity is the force field created by one massive body (like the earth) which another body (like you) will experience. (09 Oct 1997) |
| gravitational ulcer | A chronic ulcer of the leg with impaired healing because of the dependent position of the extremity and the incompetence of the valves of the varicosed veins; the venous return stagnates and creates hypoxaemia. See: varicose ulcer. (05 Mar 2000) |
| gravitational units | Of energy: gram-centimeter, gram-meter, kilogram-meter, and foot-pound. (05 Mar 2000) |
| gravitaxis | Directed locomotory response to gravity. (18 Nov 1997) |
| gravitropism | Directional growth of a plant organ in response to a gravitational field roots grow downwards, shoots grow upwards. Achieved by differential growth on the sides of the root or shoot. A gravitation field is thought to be sensed by sedimentation of statoliths (starch grains) in root caps. (18 Nov 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 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) |
| gravity, altered | A change in, or manipulation of, gravitational force. This may be a natural or artificial effect. (12 Dec 1998) |
| gravity |
(physics) the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface; "the more remote the body the less the gravity"; "the gravitation between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them"; "gravitation cannot be held responsible for people falling in love"--Albert Einstein graveness: a manner that is serious and solemn a solemn and dignified feeling
