Which describes einstein’s general theory of relativity? check all that apply. it replaced the special theory of relativity. it applies to accelerating objects. it applies to objects in uniform motion. it applies to objects in a gravitational field. it is an extension of the special theory of relativity. it applies to objects in free fall.

It applies to objects in a gravitational field. It is an extension of the special theory of relativity.

Explanation:

The special theory of relativity does not include Newton's law of universal gravitation, so the general theory of relativity is a theory of gravity that is compatible with the new relativistic principles introduced by Einstein in the special theory, such as the fact that speed of light is the speed limit for information processing, therefore Newton's remote action had to be reformulated. Special theory can be generalized to accelerated systems without the need to introduce the whole apparatus of general relativity. Due to the equivalence principle introduced by Einstein, a body in free fall cannot be distinguished from a body that is not under the action of a gravitational field, therefore both can be considered as inertial systems (with uniform motion) therefore the principles and axioms of special relativity apply.

Einstein's general theory of relativity is an extension of the special theory of relativity, and applies to objects in a gravitational field.

Explanation:

The general theory of relativity is a theory of gravity now advocated by most physicists and developed by the theoretical physicist Albert Einstein between 1907 and 1915. It is an extension of the special theory of relativity. According to general relativity, the gravity observed between two pieces is due to the masses of the pieces curving through time-space. Thus, in general relativity, gravity is interpreted as the curvature of space, that is, the change in the geometry of space.
