What is the difference between the special relativity and general relativity?

General relativity shows the relation of the observer and the acceleration, whereas special relativity shows the relation of the observer and the speed and time. General relativity considers and includes gravity, whereas special relativity does not include gravity, as no forces are acting on it.

What are the differences between the two theories of relativity?

The “General Theory of Relativity’ is related to gravity. The difference between the two theories is that the theory of general relativity throws light on the force of gravity with respect to curving four-dimensional space-time. As per Einstein, the accelerative and gravitational forces are equal and same.

What came first general or special relativity?

Einstein’s theory is divided into special and general relativity. Special relativity came first and is based on the speed of light being constant for everyone. That may seem simple enough, but it has far-reaching consequences.

Does special relativity include gravity?

In our modern time, a century after relativity was formulated, special relativity is usually understood to mean the study of motion in the absence of gravity (that is, in flat spacetime). General relativity is usually understood to mean the study of true gravity (that is, curved spacetime).

What is an example of general relativity?

General relativity. A central idea in general relativity is the “principle of equivalence.”. An example is that two people, one in an elevator sitting on the surface of the earth, and the other in an elevator in outer space accelerating at 9.8 m/s 2, will each observe the same behavior of an object they drop from their hand.

What is the special theory of relativity?

Special relativity (or the special theory of relativity) is a theory in physics that was developed and explained by Albert Einstein in 1905. It applies to all physical phenomena, so long as gravitation is not significant. Special relativity applies to Minkowski space, or “flat spacetime” (phenomena which are not influenced by gravitation).

What is Einsteins special relativity?

Albert Einstein’s Theory of Special Relativity. The special theory, on which the general theory rests, applies to all physical phenomena with the exception of gravitation; the general theory provides the law of gravitation and its relation to the other forces of nature.

What is special relativity simplified?

Special Relativity Simplified. In high school physics, we are told that the momentum of an object p is equal to the mass times the velocity, but according to special relativity, the momentum is equal to mass times the velocity times the Lorentz factor . At speeds approaching that of light, the momentum increases.
