The universal law of gravitation states that the gravitational force between two objects is inversely proportional to the square of the distance between their centers. Therefore, if you triple the distance, the gravitational force decreases by a factor of $3^2 = 9$.

According to the Universal Law of Gravitation, If You Triple
