premise: the gravitational force of a celestial object does not change the mass of an object on that planet or celestial body sent2: as the mass of a celestial object decreases , the surface gravity of that celestial object weakens sent3: a rocket is a kind of object sent4: the earth has more mass than the moon sent5: a moon is a kind of celestial object sent6: less is the opposite of more sent7: earth is a kind of celestial object sent8: as the force of gravity decreases , the weight of the object will decrease.
hypothesis: the rocket will weigh less but have the same mass on the moon than on earth
