sentences: a rocket is a kind of object & the rocket escapes the gravitational pull of earth & earth is a kind of planet ->  the rocket escaping the gravitational pull of earth is an example of an object escaping the gravitational pull of a planet  the rocket escaping the gravitational pull of earth is an example of an object escaping the gravitational pull of a planet & if an object escapes the gravitational pull of a planet, then the force of gravity on that object will change ->  the force of gravity on the rocket changes when it escapes the gravitational pull of earth  the force of gravity on the rocket changes when it escapes the gravitational pull of earth & as the force of gravity changes , the mass of the object will stay the same ->  the mass of the rocket will stay the same after the rocket escapes the gravitational pull of earth  the force of gravity on the rocket changes when it escapes the gravitational pull of earth & as the force of gravity changes , the weight of the object will change ->  the weight of the rocket will change after the rocket escapes the gravitational pull of earth  the mass of the rocket will stay the same after the rocket escapes the gravitational pull of earth & the weight of the rocket will change after the rocket escapes the gravitational pull of earth -> 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
