  • Interesting fact: In space, astronauts are unable to cry, tears can't flow down, because of the lack of gravity.
    • gravity Weight, as contradistinguished from mass; precisely, the downward acceleration of terrestrial bodies, due to the gravitation of the earth modified by the centrifugal force due to its rotation on its axis. The amount of this acceleration is about 385. 1 inches (978 centimeters) per second at the sea-level and the equator, while at the poles it is 387.1 inches. Gravity is a little less on mountains than at the sea-level, in the proportion of a diminution of one thousandth part at every two miles of elevation. There are also other slight variations of gravity, from which the figure of the geoid (which see) can be calculated. Generally speaking, gravity is in excess where the radius vector of the geoid is in excess of that of the mean spheroid. [The words gravity and gravitation have been more or less confounded; but the most careful writers use gravitation for the attracting force, and gravity for the terrestrial phenomenon of weight or downward acceleration which has for its two components the gravitation and the centrifugal force. The centrifugal force at the equator is 1/289.4 of gravity. It is everywhere exerted in the plane of the meridian at right angles to the direction of the celestial pole. The direction of gravitation in middle latitudes is inclined about 11'.5 to the radius of the earth.
