### Gravitational Fields

The force of gravity is an unscreened long range force and it can be considered as an intrinsic property of the space time related to the space time geometry We therefore start by studying the time intervals and distances in the pseudo Riemannian metric of the general relativity Then we study the motion of particles in the gravitational fields using the geodesic equations of motion
