Detailed explanation-1: -The gravitational force weakens rapidly with increasing distance between masses. The gravitational force is extremely hard to detect unless at least one of the objects has a lot of mass.
Detailed explanation-2: -When the distance between two objects increases, the force of gravity decreases.
Detailed explanation-3: -This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. This means that as you move away from an object the gravitational force decreases.
Detailed explanation-4: -Hence, when the distance between the objects is reduced to half, the gravitational force increases four times. Q.
Detailed explanation-5: -Freefall occurs where the only force acting on an object is gravity. Because gravitational acceleration on earth is constant, the distance an object falls is proportional to the time spent falling.
