The planet Jupiter is more than 300 times as massive as the 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 Earth. Can you think of an explanation for why this is so? (Hint: Let the terms in the equation for gravitational force guide your thinking.)

larger radius
weight goes up as the mass, but decreases as the square of the radius
F = GMm/r^2
