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.
