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

a universal constant relating the gravitational force,

*F*, attracting two masses,*m*_{1}and*m*_{2}, toward each other when they are separated by a distance,*r*, in the equation:*F*= G(*m*_{1}*m*_{2}/*r*^{2}); it has the value of 6.67259 × 10^{-8}dyne cm^{2}g^{-2}= 6.67259 × 10^{-11}m^{3}kg^{-1}s^{-2}in SI units. [Sir Isaac
