R is the distance between the centers of the masses. F Gm 1 m 2 r 2. Planet M mass of central body eg.
The force of gravitation calculated by these two equations between the nucleons of two adjoining atoms is practically the same because the ratio D2 D-dn2 is almost equal to one.
2gy vi2 is the square root of the quantity 2gy vi2 y is the vertical displacement in meters m or feet ft See Derivation of Displacement-Velocity Gravity Equations for details of the derivations. The proportionalities expressed by Newtons universal law of gravitation are represented graphically by the following illustration. Gravity Equation There is not one not two not even three gravity equations but many. V 2gy vi2 where.
