The force of gravity between any two objects is
G x (mass of one object) x (mass of the other one)/(distance between them)2 If the masses and distance are in SI (metric) units, then G is 6.67 x 10-11 ,
and the force is in newtons. (about 4.45 newtons makes 1 pound.)
It doesn't make any different whether the two objects are a planet and an ant, a
planet and a star, two ping-pong balls, two people, or a galaxy and a feather.
That's the amount of gravitational force that's trying to pull them together.
Let's be careful here. There's no such thing as the "amount of gravity".Gravity is the name we give to a characteristic of nature that causes aforce of attraction between every two specks of matter. So you couldask "What measures the force of gravity between an object and a planet ?"If that were your question, then I would begin an answer by saying that abathroom scale is a perfectly good thing to use to measure that force.
Your weight on a planet is determined by the strength of its gravity. Gravity is the force that pulls objects towards the planet's center. The more massive the planet, the stronger the gravity, resulting in a greater weight for objects on its surface.
Weight is the force of gravity acting on an object's mass. Because gravity varies from planet to planet, an object would weigh different amounts depending on the gravitational pull of that planet. For example, an object would weigh more on a planet with stronger gravity, like Jupiter, and less on a planet with weaker gravity, like Mars.
Mass does since it is the amount of matter in an object and it is the same everywhere. Weight is the amount of gravity force on the object, so it changes on a different planet.
The orbit of a planet (or other object) is maintained by a balance between gravity (which is trying to pull the object inwards) - and centrifugal force (which is trying to 'throw' the object out into space.

The amount of gravity that something possesses is proportional to its mass and distance between it and another object.
-- The product of the masses of the planet and the object on its surface; -- The distance between their centers of mass ... roughly the planet's radius.
F = G*m(planet)*m(object)/(r^2) where F is the gravitational force G is the gravitational constant m is mass r is the distance between the object and the center of the planet g = G*m(planet)/(r^2) where g is the acceleration due to gravity.
No mass is not the magnitude of the force due to gravity on an object. Mass is the stuff of which the object is composed. The magnitude of the gravitational forces between the object and Earth ... or whatever planet the object happens to be on ... is the object's "weight".
The weight of an object on the surface of a planet depends on ...-- The mass of the object.-- The mass of the planet.-- The distance between the center of the object and the centerof the planet, i.e. the planet's radius.
The mass of the object remains the same since it is a measure of the amount of matter in an object, but the weight changes because weight is dependent on gravity, which varies from planet to planet. If the gravitational force on the new planet is different than on Earth, the weight of the object will be different.
The force of gravity on a person or object on the surface of a planet is called weight. It is the result of the gravitational attraction between the object and the planet. Weight is measured in units of force, such as newtons or pounds.
To find the amount of gravitational force on an object you multiply the mass of the object(in kg) by the gravity(in m/s^2) of the planet. Your final units are in Newtons(N) or kg*m/s^2
The object would crash into the planet.
Linearily.
The force of gravity on a person or object at the surface of a planet is calculated by the product of the mass of the person or object and the gravitational constant acceleration for the planet. For Earth, the gravitational acceleration is 9.8 m / s^2.
