The strength of gravity from a given object is directly proportional to the object's mass and inversely proportional to the square of the distance from the center of mass. So, if we double an object's mass the gravity is double. If we triple the mass the gravity is tripled. By contrast if we double the distance we end up with one quarter the gravity. If we triple the distance we end up with only one ninth the gravity.
The formula for the strength of gravity is: g=G*M/r^2
"G" is the Newtonian gravitational constant, "M" is the mass of the object, and "r" is the distance tot he center of mass.
In the case of the surface gravity of a planet, the distance to the center of mass is the planet's radius. So if two planets have the same mass but are of different sizes, the larger planet will actually have weaker surface gravity. In most cases a larger planet will have a greater mass than a smaller one, but not always as planets vary in density. Event if the larger planet is more massive, the larger size can still result in weaker gravity.
A perfect example would be a comparison between Earth and Uranus. Uranus is about 4 times the radius and about 14.5 times the mass of Earth. From these figures we find that the gravity on Uranus is 0.906 times or 90.6% of Earth's surface gravity.

Which has the greater surface area one large cell or 27 smaller cells?
If the smaller cells' total volume is at least that of the larger cell then the smaller cells have the greater surface area.
What is size of solute?
It is the amount of surface of a solute that is exposed to the solvent. The smaller the pieces of the solute are, the larger the surface area that is exposed to the solvent.
How gravity affects us on different planets?
The larger the planet is, the more amount of gravity you will get. The smaller the planet is, the less amount of gravity you will get.
How does length and width of a potato affect osmosis and also how does the mass of the potato affect osmosis?
If a potato has a larger surface are:volume ratio, it will be affected by osmosis more quickly that a potato with a smaller surface are:volume ratio. Presumably a potato with a larger mass will have a smaller SA:Vol ratio, and as such will be less affected.
How the size of particles affect the way the particles dissolve?
The smaller the particle the faster it dissolves. This is because the process by which a solute dissolves takes place at the surface of the solvent. That means the larger the surface area of a particle or solute, the faster the solute will dissolve.
Does mercury have a smaller or larger gravity then earth?
Much smaller.
What causes the earth to have gravity?
Earth is hafly big, so it has gravity. Larger, it has more gravity. Smaller, it has less gravity.
How does mass and gravity distance effect gravity?
The larger the mass of an object, the greater the force it will exert on other objects. But as the distance from that object becomes greater, the gravitational pull becomes smaller. For example, the sun has a larger mass than the earth, so gravity on the suns surface would be much greater than on earths surface. Also, as you get further and further away from the earth, the less you are influenced by its gravity.
Is the gravity on mars smaller or larger then earth?
Gravity on Mars is substantially lower than on Earth.
Why planets are of regular in shape while meteors are irregular in shape?
Because of their larger gravity, AND their larger size. Larger gravity will allow smaller hills or other irregularities; larger size means that an irregularity of a certain size will smaller, compared to the size of the planet.
Does moon europa have gravity?
Yes. Everything has gravity. Larger and denser objects have more gravity than smaller objects that are less dense.
Is the Moon smaller than Earth the same size as Earth or larger than Earth?
The Moon is considerably smaller than the Earth. Its volume is about 2% of the Earth's. Its mass is only about 1.2% of the Earth's. Its surface gravity is about 1/6 that of the Earth.
Is mass larger on bidder planets or smaller?
Mass does not change with gravity. Weight increases on BIGGER planets and decreases on smaller planets.
Does a smaller rock a have higher or lower percentage of surface area than a larger rock?
It depends on percentage related to WHAT! You cannot express surface area as a percentage of volume since the dimensions are different. So the only percentage you can have is the suface area of the smaller rock as a percentage of the surface area of the larger rock. In that case, the answer, not surprisingly, is that the smaller rock has the smaller percentage surface area.It depends on percentage related to WHAT!

Which has a more powerful gravity a small planet or a large planet?
It would depend on the mass of the planets. The surface gravity of a planet is directly proportional to its mass and inversely proportional to the square of its radius. If two planets have the same mass but different sizes, the smaller planet will have stronger gravity because the surface is closer to the center of mass. Conversely, if two planets are of the same size, the one with more mass will have stronger gravity. Since larger planets usually have more mass than smaller ones they usually have stronger gravity, though not always.
Which has the greater surface area one large cell or 27 smaller cells?
If the smaller cells' total volume is at least that of the larger cell then the smaller cells have the greater surface area.
The Relative Surface Gravity on Earth is what?
The question doesn't include enough information to make an answer possible.Whenever you talk "relative", you then must specify: relative to what.The weight of an object on the Earth's surface is much smaller than the sameobject's weight on the sun's surface, but much larger than its weight on thesurface of a bowling ball.
