Gravitational pull is greater on earth . As weight = mass × g so we have more weights on earth than on moon.
Explanation:
This is because gravitational force is immediately proportional to the mass of an object. Greater the mass, greater will be the gravitational force exerted by it and thus, more will be our weight. As the moon has secondary mass than the earth, it has a lighter gravitational influence and hence, we weigh less on the moon.
