The planet Jupiter is more than 300 times as massive as Farth, so it might seem that a body on the surface of Jupiter would weigh 300 times as much as on Earth. But it so happens that a body would scarcely weigh three times as much on the surface of Jupiter as it would on the surface of the Earth, Can you think of an explanation for why this is so? (Hint: Ler the terms in the equation for gravitational force guide your thinking.)
