What is the difference between general relativity and special relativity in the field of physics?

General relativity and special relativity are both theories proposed by Albert Einstein to explain the behavior of objects in space and time. Special relativity deals with the relationship between space and time in the absence of gravity, while general relativity extends this to include the effects of gravity on the curvature of spacetime. In essence, special relativity focuses on objects moving at constant speeds, while general relativity considers the effects of gravity on the motion of objects.
