Isaac Newton developed a formula for measuring weight on Earth. The formula indicated the gravitational forces beween mass structures.
However He refused to give an answer on what was the cause of the mechanism of Gravitation.
It was Keppler that initially established the relationship of planetary motion,relative to the period of the orbits and velocity of the orbiting planets.He first determined that the orbits are of an elliptical nature but did not explain why,and till to day no one has exactly given the mechanism of why.

Gravity causes objects to "fall" toward a body of significant mass as (g>n2 (pi) a) where a = accelleration of the gravitational constant of r (not the other r but the one r that speaks to rates of gravitational stuff). The force imposed upon the orbiting body is (theta/hypotenues of my left nut (x) divided by the GNP of Denmark which causes the orbit to be somewhat deformed as an elipsis. That's why on Earth, we experience a lunar paragee every 16.3 years.
