The force is proportional to the mass and inversely proportional to the square of the distance, according to Newton's law of gravity.
It was demonstrated to be correct after Newton predicted from theory that a planet under this force must travel in an elliptical orbit that follows Kepler's 3 laws of planetary motion. So the theory fits the observations, and it has lasted since 1687 with a minor correction by Albert Einstein.
What else can I help you with?
What 2 things effect the gravitational pull of the planets?
Mass & distance.
How do mass and distance affect gravitaional pull?
Mass and distance dont effect gravitational pull. Its always 9.8 m/s.
What other planets have a gravitational pull?
Not only planets but everything with mass, no matter how large or small, has a gravitational effect.
How does the density of an object effect its gravitational pull on other objects example when a star's density increases its gravitational pull increases on other objects?
Mass, not density, and the closeness of objects, affects an object's gravitational pull. Density is not dependent on an object's size, but mass is. The more massive an object, and/or the closer an object is to another, the greater its gravitational pull.
Why can you feel and see the effect of Earth's gravitational pull on you but you cannot feel or see the effect of your teachers's gravitational pull on you?
It may have something to do with the fact that the gravitational pulls are proportional to the masses of the earth and your teacher and that your teacher has considerably less mass than the earth!

Why can you feel and see the effect of Earth's gravitational pull on you but you cannot feel or see the effect of you teacher's gravitational pull on you?
The difference lies in the mass and distance between you and your teacher. Earth is much more massive and closer to you than your teacher, so its gravitational force is much stronger. Additionally, the force is proportional to the mass of the objects involved, therefore Earth's gravitational pull has a more noticeable effect on you compared to your teacher's.
What materials have gravitational pull?
All materials with mass exert a gravitational pull.
What determine the gravitational pull of a object?
An object's gravitational pull is determined by the object's mass.
Does every object have a gravitational pull on another object?
Yes. A gravitational force attracts every mass toward every other mass.
What affects the earths gravitational pull?
Mass and density. The more mass an object has the higher its gravitational pull is. Some places on Earth are more dense than others. therefore they have more mass which can slightly increase the gravitational pull at that area.
What are the two factors that influence the gravitational pull between two objects?
The two factors that influence the gravitational pull between two objects are the mass of the objects and the distance between them. The greater the mass of the objects, the stronger the gravitational pull, while the farther apart the objects are, the weaker the gravitational pull.
