Barology :: Barology (n.) The science of weight or gravity.

Foot Pound :: Foot pound () A unit of energy, or work, being equal to the work done in raising one pound avoirdupois against the force of gravity the height of one foot..

Gravitation :: Gravitation (n.) That species of attraction or force by which all bodies or particles of matter in the universe tend toward each other; called also attraction of gravitation, universal gravitation, and universal gravity. See Attraction, and Weight..

Lactometer :: Lactometer (n.) An instrument for estimating the purity or richness of milk, as a measuring glass, a specific gravity bulb, or other apparatus..

Urinometer :: Urinometer (n.) A small hydrometer for determining the specific gravity of urine.

Gravitational :: Gravitational (a.) Of or pertaining to the force of gravity; as, gravitational units..

Ponderosity :: Ponderosity (n.) The quality or state of being ponderous; weight; gravity; heaviness, ponderousness; as, the ponderosity of gold..

Silver :: Silver (n.) A soft white metallic element, sonorous, ductile, very malleable, and capable of a high degree of polish. It is found native, and also combined with sulphur, arsenic, antimony, chlorine, etc., in the minerals argentite, proustite, pyrargyrite, ceragyrite, etc. Silver is one of the noble metals, so-called, not being easily oxidized, and is used for coin, jewelry, plate, and a great variety of articles. Symbol Ag (Argentum). Atomic weight 107.7. Specific gravity 10.5..

Bismuth :: Bismuth (n.) One of the elements; a metal of a reddish white color, crystallizing in rhombohedrons. It is somewhat harder than lead, and rather brittle; masses show broad cleavage surfaces when broken across. It melts at 507¡ Fahr., being easily fused in the flame of a candle. It is found in a native state, and as a constituent of some minerals. Specific gravity 9.8. Atomic weight 207.5. Symbol Bi..

Magnesium :: Magnesium (n.) A light silver-white metallic element, malleable and ductile, quite permanent in dry air but tarnishing in moist air. It burns, forming (the oxide) magnesia, with the production of a blinding light (the so-called magnesium light) which is used in signaling, in pyrotechny, or in photography where a strong actinic illuminant is required. Its compounds occur abundantly, as in dolomite, talc, meerschaum, etc. Symbol Mg. Atomic weight, 24.4. Specific gravity, 1.75..

Brachystochrone :: Brachystochrone (n.) A curve, in which a body, starting from a given point, and descending solely by the force of gravity, will reach another given point in a shorter time than it could by any other path. This curve of quickest descent, as it is sometimes called, is, in a vacuum, the same as the cycloid..

Sageness :: Sageness (n.) The quality or state of being sage; wisdom; sagacity; prudence; gravity.

Geotropism :: Geotropism (n.) A disposition to turn or incline towards the earth; the influence of gravity in determining the direction of growth of an organ.

Sink :: Sink (v. i.) To fall by, or as by, the force of gravity; to descend lower and lower; to decline gradually; to subside; as, a stone sinks in water; waves rise and sink; the sun sinks in the west..

Gravity :: Gravity (a.) The state of having weight; beaviness; as, the gravity of lead..

Burlesque :: Burlesque (a.) Tending to excite laughter or contempt by extravagant images, or by a contrast between the subject and the manner of treating it, as when a trifling subject is treated with mock gravity; jocular; ironical..

Solemnness :: Solemnness (n.) The state or quality of being solemn; solemnity; impressiveness; gravity; as, the solemnness of public worship..

Tungsten :: Tungsten (n.) A rare element of the chromium group found in certain minerals, as wolfram and scheelite, and isolated as a heavy steel-gray metal which is very hard and infusible. It has both acid and basic properties. When alloyed in small quantities with steel, it greatly increases its hardness. Symbol W (Wolframium). Atomic weight, 183.6. Specific gravity, 18..

Glucinum :: Glucinum (n.) A rare metallic element, of a silver white color, and low specific gravity (2.1), resembling magnesium. It never occurs naturally in the free state, but is always combined, usually with silica or alumina, or both; as in the minerals phenacite, chrysoberyl, beryl or emerald, euclase, and danalite. It was named from its oxide glucina, which was known long before the element was isolated. Symbol Gl. Atomic weight 9.1. Called also beryllium..

Opal :: Opal (n.) A mineral consisting, like quartz, of silica, but inferior to quartz in hardness and specific gravity..
