Gravity on a planet varies because it depends upon mass and distance. Mass is proportional to gravity is and every planet have different sizes and masses.
F = G(mass1*mass2)/D squared.
(G is the gravitational constant, which has the same value throughout our universe.)
Gravity is directly proportional to mass.
The gravitational force on an object at a standard distance is proportional to the mass of the planet.
The gravitational force on an object at a standard distance is proportional to the mass of the planet.
The gravity of a planet is directly proportional to its mass, and inversely proportional to the square of the distance from the center of mass. For the gravity on the surface of the planet, the distance is just the planet's radius. Thus, if a planet has three times the mass, it has three times the gravity. If you are three times as far away, the gravity decreases by a factor of nine.
It does not. Mass is independent of where an object is. Weight, however, will vary in direct proportion to the planet's gravity.
The larger the planet mass, the bigger force of gravity it has.
Gravity is directly proportional to mass.
No, because the mass of Venus does not vary.

Objects have a gravitational pull proportional to their mass.
