The accepted average or mean radius is 6371 km. Note: Since the Earth is not a perfect sphere, the radius varies in different locations, including being greater at the equator and less at the poles. You can find the value of g by substituting the following items into the equation: This is the gravity constant or acceleration due to gravity. R E is the separation between the center of the Earth and an object on its surface it is also the radius of the Earth.G is the Universal Gravitational Constant.F is the force of attraction at the surface of the Earth.Thus, if you considered a hypothetical point object of mass m that was at the surface of the Earth, the force between them would be: One assumption made is that the mass of each object is concentrated at its center. ( See Universal Gravitation Equation for more information.) R is the separation of the centers of the objects in meters (m). ![]() M and m are the masses of the objects in kilograms (kg).G is the Universal Gravitational Constant: 6.674*10 −11 m 3/s 2-kg. ![]()
