premise: a rocket is a kind of object sent2: the rocket escapes the gravitational pull of earth sent3: as the force of gravity changes , the mass of the object will stay the same sent4: if an object escapes the gravitational pull of a planet, then the force of gravity on that object will change sent5: earth is a kind of planet sent6: as the force of gravity changes , the weight of the object will change.
hypothesis: the mass of the rocket will stay the same and the weight of the rocket will change after the rocket escapes the gravitational pull of earth
