To do that, we will go in a journey to see what the old (Newtonian) and the new (Einstein) picture of gravity is. And to season that, we will finish by introducing quantum Gravity. I will begin by defining the Keplers laws for planetary motion, which Depending on it Newton created his theory for gravity, and we finish the section by Newtons gravity failure. Then I will start our discussion for Einsteins picture of gravity (general relativity), and cover rather some important topics, such as; Equivalence principle, Space-Time geometry, Einstein Field Equation...Etc., and I will finish the section by Einsteins answer to Newtonian failure. Finally I will give a very simple introduction to Quantum Gravity, and mainly discuss the some of the problems that phases the theory to be perfect.

Moreover, the mass of the string is negligible in comparison with that of the bob. Under these conditions the mass of the bob may be regarded as concentrated at its center of mass, and the length of the pendulum is the distance to this point from the axis of suspension. When a simple pendulum swings through a small arc, it executes simple harmonic motion of period T given by the equation :
