acceleration of gravity
: acceleration of a body falling in a vacuum under the influence of the earth's gravity expressed as the rate of increase of velocity per unit of time, its value at sea level in latitude 45 degrees being 980.616 centimeters per second per second which is designated as g45 as distinguished from g0 = 980.665 centimeters per second per second, an arbitrary value adopted in 1901 by the International Committee of Weights and Measures — abbr. g

Physics.
the acceleration of a falling body in the earth's gravitational field, inversely proportional to the square of the distance from the body to the center of the earth, and varying somewhat with latitude: approximately 32 ft. (9.8 m) per second per second. Symbol: g Also called gravity.
[1885-90]

acceleration of gravity,
the rate of change in velocity of a freely falling body, caused by the force of gravity. The rate varies slightly with changes in latitude and altitude. At sea level, in the approximate latitude of New York City, it is 32.16 feet per second in each second of the fall of the body.
