can anyone show a graph or an equation showing the gravitational pull of the earth in relation to distance?

Answer 1

gravity is an inverse square law type graph , you can plot it at y=1/x^2
try this site http://hyperphysics.phy-astr.gsu.edu/hbase/forces/isq.html

another graph is available here

Answer 2

F = m1m2G / r^2

Where m1 and m2 are masses, G is the gravitational constant, and r is the separation distance between the two objects.

If you seek just the acceleration due to gravity, it can be simplified to:

a = MG / r^2, where M is the mass of the earth, etc.
