(redirected from acceleration of gravity)
Also found in: Dictionary, Thesaurus, Financial, Encyclopedia, Wikipedia.


The force of attraction between any two bodies in the universe, varying directly as the product of their masses and inversely as the square of the distance between their centers; expressed as F = Gm1m2l -2, where G (newtonian constant of gravitation) = 6.67259 × 10-11 m3 kg-1 s-2, m1 and m2 are the masses (in kg) of the two bodies, and l is the distance separating them in meters.

(grăv″ĭ-tā′shŭn) [L. gravitas, weight]
