Two objects of the same mass are on two different planets. planet a has a force of gravity that is weaker than that of planet b. how will the weights of the objects compare to each other? the weights of the objects will be the same. the weight of the object on planet a will be greater than the weight of the object on planet b. the weight of the object on planet a will be less than the weight of the object on planet b. this cannot be determined without knowing the actual mass of the objects.
