newtonian constant of gravitation


new·to·ni·an con·stant of grav·i·ta·tion (G),

a universal constant relating the gravitational force, F, attracting two masses, m1 and m2, toward each other when they are separated by a distance, r, in the equation: F = G(m1m2/r2); it has the value of 6.67259 × 10-8 dyne cm2 g-2 = 6.67259 × 10-11 m3 kg-1 s-2 in SI units. [Sir Isaac Newton]
