Universal Gravitational Constant

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

The universal gravitational constant, abbreviated as G, is the proportionality constant used in Newton's Law of Universal Gravitation.  This constant is very difficult to measure with any high accuracy.

\(\large{ G = 6.67384  \; \left( 10^{-11} m^3  kg^{-1}  s^{-2} \right) \; = \; 6.67384  \; \left( 10^{-11} Nm^2  kg^{-2} \right)  }\)
