It's a question for a physics project in for Thursday, an im really confuzed as to what the answer is! Help please!

Gravitational pull is inversely proportional to the square of distance.
Alternately, you could say gravity decreases as the square of distance. Take your pick... they mean the same thing.
The exact formula, as the person above mentioned, is
g = m1*m2/d²

I'm assuming that this question pertains to Newtonian mechanics. If so the equation for force of gravity is:
F=\frac{GMm}{r^2}
Where G is the gravitational constant
M is the mass exerting the force (assuming it is fixed)
m is the mass of the object being forced
r is the distance between them
This equation shows an inverse square relationship between the distance and force. That is, for an increase in distance of n times the force is multiplied by \frac{1}{n^2}.

The formula is :
Force = gravitaional constant * mass of first object * mass of 2nd object ALL DIVIDED BY the distance between them -- squared.
So, as you (object 2) get further away from object 1, the force gets smaller (because the distance is in the denominator of the formula), AND it gets smaller, *faster*, because it is squared.
If you move 1 foot away the force is what it is, but if you move 2 feet away the force is 1/4 of what it was a 1 foot away. If you move 3 feet away, the force is 1/9 of what it was at 1 foot, and so on. (4 is 2-squared, 9 is 3-squared).

The gravitational force between two objects is
F=G M m / r^2, where G is a constant, M and m are the masses of the two objects, and r is the distance between their centers of mass.

There is an equation F = G(m1m2/r2) where r is distance and G = 6.673 ´ 10-11 Nm2/kg2. and m1 and m2 are the masses of the attraction bodies. F is the force.

Generally, the further away you are from the source, the less gravity effects you. On Earth, we are at 1G. In orbit its far less.
Oh, in all things being gravity, size DOES matter. The bigger the object, the higher the gravity. On Juipter, I would weigh in at 1,500 lbs. Talk about crushed leggs...ouch

The closer to an object you get, the stronger energy you will need to move away from it. i.e. a space shuttle does not need that much thrust once it reaches 100 km in the air.

The closer you are, the stronger the pull.
