Does gravity increase or decrease when distance increases and what will be the effect on the acceleration due to gravity of the earth it is compressed to the size of the moon?
When the distance between two objects increases, the force of gravity decreases. When the earth is compressed to the size of the moon, the gravity of the earth and the value of acceleration due to gravity increase by 14 times. As the value of g is inversely proportional to the distance from the center of the earth, thus the value of g reduces when altitude becomes very high.
