# Is there any relationship between the mass of a planet and its gravitational field strength?

The larger the mass of any object, the larger its gravitational field strength, the same goes for planets.

The relative strength of its gravitational pull is directly proportional to the planet's mass.

The relationship between the mass of a planet and its relative strength of gravitational pull is that they are directly proportional. The equation for the force of gravity between two bodies is F = GMm/r^2, where F is the force of gravity, G is the gravitational constant, M is mass 1, m is mass 2, and r is the distance between the objects.

There is a point where the gravitational field strength of both planet or object is equal, hence they cancel off each other, resulting in zero net gravitational field strength.

Saturn's gravitational strength at the equator is most similar to Earths at 1.065g

The mass of the planet is all you need to know. That, along with the mass of the other object and the distance between their centers, tells you the strength of the force between them.

The relationship between mass and weight is that mass is constant in any environment, whereas weight changes from planet to planet because the gravitational pull is different, from which the weight depends on.

The gravitational strength of Saturn is close to Earth's. Earth's surface gravity is 1g while Saturn's is 1.065g which is surprising for such a large planet.

It can be calculated on the basis of the planet's mass and its radius.

Yes. It's about 38% of the strength of Earth's gravity.

well the earths gravitational on the sun and the moon is,the earth revolving around the sun,andthe sun gravity pulls the strength of earth and the moon revolving around the planet that we call EARTH.

Gravitational field strength is equal to mass of planet times G divided by the radius squared. That gives you the field strength per unit mass, eg: in Newtons per kilogram.

The gravitational field strength of a planet multiplied by an objects mass gives us the weight of that object, and that the gravitational field strength, g of Earth is equal to the acceleration of free fall at its surface, 9.81ms &minus; 2.

The mass of planets is tabulated on wikipedia. The gravitational strength is measured by the mass.

The weight of an object represents the magnitude of the gravitational force exerted on the object by the planet, less the effect of immersion in any fluid.

Yes. The strength of the mutual gravitational force between the earth and every kilogram of mass on it is the same. To put it another way for emphasis: A gram of cheese, a gram of bricks, and a gram of feathers all have the same weight when they're on the same planet.

I only know a few; Mars - 3.73 N Jupiter - 25.93 N Saturn - 1.16 N if gravitational field strength' means the acceleration produced by a planet's mass, a = GMp/R&sup2; where G is the universal gravitational constant, Mp is the mass of the planet and R is the distance from the center of mass of the planet. just find the mass of the planet, g is constant, and then divide by the square of the distance....

The gravitational force between any two object is given by Newton's basic formula for gravity: F = G M1 M2 / R2 If the masses M1 and M2 are in kilogrammes and the distance between the objects R in metres, and the gravitational constant G is 6.670 x 10 to the power of -11, the answer is in Newtons.

THe larger the planet, the more gravitational pull it has.

The planet IS the source of gravitational (potential) energy.

Weight is actually force in a fixed setting. In the context of a relatively large and uniform gravitational field (such as being on the surface of the planet), weight is the force along the line between the center of the gravitational field and the center of the object. That is, the weight of an object in such a gravitational field is the strength of that field multiplied by the mass of the object.

Gravitational force depends only on the masses involved, and on the distance. Thus, to DECREASE the gravitational force, you would have to reduce the mass of the planet or the object (take some stuff away from it); or increase the distance.
