gravitation
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 g.) = 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. [L. gravitas, weight]
