Why does jupiter has a high gravity?

[squarebear]

Because it is the largest planet in our solar system. The heavier the body, the stronger the gravity.

[jomifl]

Squarebear it is mass not weight that determines the strength of a gravitational field. Weight is a function of mass and gravity.

My apologies

"idea of the relative size of your Earth relative to Jupiter"

Your earth? Is it not yours as well Eddie lol ;-)

[Vagrant]

Because it's heavy (or massive, if you want to be pedantic). Last time I was there, I struggled to keep my test1cles from touching the floor of my spacecraft ...

Eddie is not of this world.

Cor blimey, that betelgeuse is a big bugger!

[blackeyed]

Thank you all for answering.
so all the planets bigger than earth have a higher gravity(than earth)?
and when did squarebear mention weight??

[jomifl]

weight was implied in the use of the word heavy. I forgot to mention when 'correcting' Squarebear that distance from the centre of gravity is also a determinant of weight as well as mass.

It's not size but mass that matters. A planet could be bigger than the earth but not as massive due to the density of the matter it was made up of.
So you could say: The more massive a planet is the higher is the force of gravity on that planet.

I think it's fascinating actually.

[jake-the-peg]

The difference between mass and weight is a rather crucial concept in physcis razza

If you haven't got anything productive to add perhaps you should stick to other threads

[jomifl]

It is possible to have a planet with a greater mass than the earth that is a lot less dense so that when standing on the surface you would be so far from the planet's centre of gravity that you would weigh less than you would on earth.

Razza..some people are curious.. it is a sign of intelligence.

[mibn2cweus]

Although it's much bigger and has a lot more mass than the Earth, you'd weigh less on Uranus . . .

Thanks mibn.. I couldn't think of an example of a more massive planet with a smaller surface gravitational force than earth .
