Detailed explanation-1: -When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
Detailed explanation-2: -Gravity is affected by the size of objects and the distance between objects. A measure of the amount of matter in an object is mass. An object with a greater mass falls faster than an object with a smaller mass. When the distance between two objects increases, the force of gravity decreases.
Detailed explanation-3: -Two factors determine the magnitude of the gravitational force between two objects: (1) their masses and (2) the separation distance between them. The size of the force is proportional to the product of the masses of the two objects.
Detailed explanation-4: -Newton’s law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them.
Detailed explanation-5: -Since gravitational force is inversely proportionalto the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
