# Is gravity determined by mass or size or both?

Since gravity is basically a force then, it is determined by both mass and size. Also weight.

The escape velocity is determined by the gravity of the planet which in turn is determined by the mass and size of the planet

A lot of scientist's believe that gravity is determined by the size of the planet. I however, believe that gravity is determined by the speed the planet is moving around the star and the speed of the planets rotation.

The mass of an atom is determined by the size of the atom, and the bigger the atom, the more mass it has.

The force of gravity is determined by (a) the masses involved, and (b) the distance between the masses. Of course, in the case of a planet for example, you can determine the mass if you know its average density and its size. Note that for a homogeneous sphere, the force of gravity on an object outside the planet is the same as if all mass were concentrated in the center.

Gravity is completely responsible for planetary motion. The shape and size of each orbit, and the speed of the planet at every point in its orbit, taken along with the mass of the sun, are completely determined by the behavior of gravity.

There is a mathematical relationship between gravity and weight not mass. Mass is some thing that you always have, it doesn't change. But weight is determined by the size of the planet that they are on, bigger planets like Saturn and Jupiter get more gravity therefore making a person's weight differ

Yes. everything with mass has gravity. Something the size of an everyday rock, though, does not have enough mass for its gravity to be noticeable.

Size itself does not affect gravity, but a larger planet is almost always going to have more mass, and more mass will mean more gravity.

The mass of The Earth is determined by the size. and we have less gravity. which controls movement in the object, and in Newton's laws it explains that every Action has a reaction so what you do to an object will have an effect on it.

The orbital circumference of a planet is determined by both the mass and size of a planet. Although a planet will orbit the sum in an eliptical sphere shaped orbit, the circumference of these are almost always relative to the mass and density of the planet. It is also determined on how far away it is from the sun. The orbital circumference of a planet is determined by both the mass and size of a planet.

They are all different since Mass is determined by size and composition.

No. The gravity on a planet depends on its size and mass.

The volume of an atom is determined by the size of its electron cloud. Most of the mass of an atom is in the nucleus.

The larger the mass of the planet, the greater the force of its gravity.

No. The strength of gravity on a planet depends on its size and mass.

Distance: The closer together the stronger gravity. The further apart the weaker gravity. Size: The greater the mass, the stronger the gravity.

The mass of the planet, the mass of the sun and the distance between the two.

The pull of an object's gravity is proportional to its mass, if measured at a standard distance.

There is gravity on all planets. The strength of that gravity varies depending on the size and mass of each planet.

Einstein showed that Newton's viewpoint -- that gravity was simply a force between two objects, a force whose size is determined by the mass and distance between the objects -- was only an excellent approximation. Einstein showed that gravity was instead a warping of space and time by the presence of mass (more precisely, any form of energy).

If Earth doubled is mass but remained the same size, gravity at the surface would double.

Gravity doesn't depend on size and shape of objects, it depends on mass. Gravity is an invisible force which causes objects to move towards each other and gravity depends on the mass of the object.

The one with the biggest mass and smallest size has.
