Final answer:
The difference in weight is due to the gravitational force, with Jupiter having more gravitational force than Earth.
Step-by-step explanation:
The property of the objects responsible for the difference in weight is the gravitational force. Jupiter has more gravitational force compared to Earth, which is why the kilogram mass weighs more on Jupiter. The gravitational force is directly proportional to the mass of an object, so the more massive an object is, the stronger the gravitational force acting on it.
Jupiter's mass is approximately 318 times greater than Earth's mass, and its size is about 11 times larger than Earth's diameter. This large mass and size result in a stronger gravitational force on Jupiter.
