Log g surface gravity

WitrynaLocal gravitational field strength is given by g, the force acting on a mass of 1 kilogram at the surface, according to the formula g = GM/r 2, where M is the mass of the body, r its radius, and G the gravitational constant (= 6.67 × 10 –11 newton. meter squares, Nm 2). Thus greater mass means greater surface gravity, but greater diameter ...
