what is a equation that relates universal gravitational constant to the accleration of free fall at the surface of the earth

Question

egenriether · Answer

newtons gravitational equation gives the force of attraction of two masses.  One could be the earth.  Then Newton's second law of motion tells what that force does to objects.

$$T^4=(4piL/g^2) (k-2d)$$
change to the form y=mx+c where y=T^4, x=d, L=180

What? Is this a general question? Free fall at the surface of the earth usually implies neglecting the variation in gravity. http://en.wikipedia.org/wiki/Newton's_law_of_universal_gravitation
