Question

Explain the difference between Special and general theory of Relativity.

Answer 1

1/ Special relativity (SR) doesn't include gravity, whereas general relativity (GR) does. 2/ In SR, the laws of physics are the same for all inertial coordinate systems, that is those in which Newton's First Law of Motion is true

Answer 2

General relativity theory published in 1916 is based on the same theory of special relativity. The distinction is that general theory explains the force of gravity in terms of a curving four-dimensional space-time. According to Einstein the forces of acceleration and gravity are equivalent.
