GRAVITY

n.[L. gravitas, from gravis, heavy. See Grave. ] 1. Weight; heaviness.
2. In philosophy, that force by which bodies tend or are pressed or drawn towards the center of the earth, or towards some other center, or the effect of that force; in which last sense gravity is synonymous with weight.
Gravity is the tendency of great bodies to a center, or the sum or results of all the attractions of all the molecules composing a great body.
3. Specific gravity, the weight belonging to an equal bulk of every different substance. Thus the exact weight of a cubic inch of gold, compared with that of a cubic inch of gold, compared with that of a cubic inch of water or tin, is called its specific gravity. The specific gravity of bodies is usually ascertained by weighing them in distilled water.
4. Seriousness; sobriety of manners; solemnity of deportment or character.
Great Cato there, for gravity renowned.
5. Weight; enormity; atrociousness; as the gravity of an injury. [Not used. ]
6. In music, lowness of sound.

4. (Physics )

 

Defn: The tendency of a mass of matter toward a center of attraction; esp. , the tendency of a body toward the center of the earth; terrestrial gravitation.

 

5. (Mus. )

 

Defn: Lowness of tone; -- opposed to acuteness. Center of gravity See under Center. -- Gravity battery, See Battery, n., 4. -- 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.
