Detailed explanation-1: -So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled.
Detailed explanation-2: -The only thing we know that affects a body’s gravity is the amount of mass it contains. So to change Earth’s gravity we would need to add or remove mass from our planet. But to make a noticeable change, we would need to move vast amounts of material. Another factor is the rate at which our planet rotates.
Detailed explanation-3: -Hence, when the distance between the objects is reduced to half, the gravitational force increases four times.
Detailed explanation-4: -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.
