Gravitational Force

          It all started when a 22 year old boy who returned home from his college discovered most of the understood fundamental of physics while dealing out with the force of attraction between the two bodies. Gravitation has been defined as the force experienced by any two bodies in the universe by virtue of their mass. The gravitational force was first experienced by the great scientist Issac Newton. When an apple fell on his head he realized that the Earth pulls everybody towards itself. Later, he concluded that everybody in the universe attracts each other which he named as gravitational force.
