Relatividade: diferença fundamental entre a relatividade restrita e geral

Abstract

This paper presents the historical issues that contributed to the emergence of special and general relativity and the main difference between the two theories. To this end, the historical factors that triggered the formulation of relativity and Albert Einstein's assumptions are highlighted throughout their development. Next, the discussion of the distinction between the theories is presented in a simple way in the last chapter, in which special relativity deals with objects in motion and at speeds close to that of light and also works with inertial reference frames, while general relativity expands this theory, incorporating gravity and the curvature of space-time, describing how gravity is an aspect of space-time and affects the movement of bodies. The paper also presents in a conceptual way the Schwazchild space-time metric for solving Albert Einstein's field equation and this is briefly discussed in its tensor form.
