SOLAR SYSTEM

Detailed explanation-1: -The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.

Detailed explanation-2: -The strength of gravity between two objects depends on two factors: the masses of the objects and the distance between them. The force of gravity between two objects is greater if the objects are closer together.

Detailed explanation-3: -Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

Detailed explanation-4: -The two variables that affect the strength of gravity are mass and the radial distance of separation.

Detailed explanation-5: -Hence, the two factors are the masses (m1 and m2) of the objects and the distance (R) between the objects.
