On which gravitational force depends
Explain in short on which the gravitational force depends on?
Expert
The Gravitational force mainly depends on the distance and mass. Therefore the formula for evaluating gravitational force among the two objects with a specific distance: G [(mass 1) (mass 2)]/distance squared. G is the universal gravitational constant: 6.67x10 rose to -11 power.

Parsec: The unit of distance stated as the distance pointed by an Earth-orbit parallax of 1 arcsec. It equals around 206 264 au, or about 3.086 x 1016 m
Spin-orbit effect: The effect that causes atomic energy levels to be split since electrons contain intrinsic angular momentum (that is spin) in summation to their extrinsic orbital angular momentum.
Super fluidity: The phenomenon by which, at adequately low temperatures, a fluid can flow with zero (0) viscosity. These causes are related with the superconductivity.

Null experiment: The experiment which, after being performed, yields no outcome. The null experiments are just as significant as non-null experiments; when current theory predicts an observable result (or predicts there must be no observable result),
