Does the amount of gravity of each planet vary depending on it's size? When we r in moon, our weight decreases. So, when we go to Jupiter does our weight increase?

Yes and no. The Gravitational Force is given in g = GM / r^2, where G = 6.67*10^-11, M = mass of planet, and r = radius in metres. So the G increases if the mass increases, or the radius decreases. If the moon had the same mass as us, you would weight a lot heavier on it than on Earth. But since it is a lot lighter than smaller than us, the g on the surface of the moon is less than that of ours, and since weight = mass X gravity, you weigh less.

Gravity depends on mass, not size, and everything that has mass has gravity (more mass means stronger gravity). Yes, your weight would increase if you went to Jupiter, because Jupiter is much more massive than the Earth.

wieght doesnt depend on gravitational force that much. on earth we hav atmosphere above us which creates lots of pressure on us thus increasing our weight whereas on moon there is no atmosphere or air hence so our weight on moon decreases.
jupiter is still not very known to human and will take a long time to be familiar wid such conditions about jupiter.and gravitational force exists between all bodies rather big or small even two balls hav grvtatnl force but it is almost negligeble but it increases wid the mass and the size of the object.
reply me if u r satisfied wid my ans. or send me ur furhter query
bye

The mass of each planetary body determines the force of gravity it exerts on objects near it. And yes you would weigh more on Jupiter than on Earth, except Jupiter likely has no solid surface for you to stand on a scale to see what you weigh, but you can compute it using g= m1 * m2/ r ^ 2.

HI,
Yes the size does have an effect which is related to the mass. Yeah you will be a lot heavier on Jupiter. Also you would be almost negligible in terms of weight on pluto.

Gravitational force is the most unknown and still the most important force of the universe!
It is related to mass, according to Aristotle! Thus, the more mass, the larger the gravitational force!

the particles of gravity known as gravitons are so small that they can show there effect only on larger quantities.as they interact with mass continuously,the gravitational force increase with mass..

not its size but its mass. yes, on jupiter, you will be heavier because its gravity is pulling harder on you than if you were on earth.

Due to the presence of metals and other magnetic substances in a concentrated manner
