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.

Weber: Wb (after W. Weber, 1804-1891): The derived SI unit of magnetic flux equivalent to the flux that, connecting a circuit of one turn, generates in it an electromotive force of 1 V as it is decreased to zero at a uniform rate in a period of 1 s; i

Roche limit: The position about a massive body where the tidal forces due to the gravity of the primary equivalent or exceed the surface gravity of a specified satellite. Within the Roche limit, such a satellite will be interrupted by tides.
