Why is gravity is lower on the Moon than on the Earth?
the force of gravity is between 2 masses is (m1 x m2) x g / d squared, where m1 and m2 are the 2 masses and d is the distance between them and g is the gravitation constant for the units that you a using (metric / imperial) as the mass of the earth is 6 times the mass of the moon it exerts a gravitation force that is 6 times bigger than the moon
