what has more force of gravity? The moon or Jupiter?

Question

maniacpokemon43 · Answer

my best guess is the moon but im not sure

anonymous · Answer

well the moon has much smaller gravitational pull than that of earth.. but jupiter on the other hand has a gravitation pull 3 times stronger than that of the earth.. you jump on jupiter, be careful ,you could probably rip off your pants :)

anonymous · Answer

its almost 3 times.. but definitely stronger than that of the moon. :)

you cannot draw the conclusion that you did from the equation

you can have a very large mass - but if the radius is large then the force will be smaller.

Also - your equation is not correct - it should be GMm/r^2
where M and m are the masses of the 2 bodies involved

@maniacpokemon43
the "Force" due to gravity depends on the mass of both the planet (or other body) AND the mass of the object being 'weighed'

For the SAME object then you need to look at the equation above:
Gm is the same in both cases so it is the value of M/r^2 which defines which body has the higher gravitational force at its surface

the MASS of Saturn is nearly 100 times that of earth, but the force of gravity at its surface is very nearly the SAME as earth, because it is much less dense and has a huge radius.
