What is the main difference between special relativity and general relativity?
Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature. It applies to the cosmological and astrophysical realm, including astronomy.
What is general theory of relativity for dummies?
What is general relativity? Essentially, it’s a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.
What is the special and general theory of relativity?
Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels, according to Wired.
What is the difference between general and special relativity quizlet?
What is the principal difference between the theory of special relativity and the theory of general relativity? Special relativity applies to frames of reference moving at constant velocity, whereas general relativity includes accelerating reference frames.
Is E mc2 special or general relativity?
theory of special relativity
E = mc2, equation in German-born physicist Albert Einstein’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other.
What is the difference between the two theories of relativity?
The main difference between general relativity and special relativity is that general relativity is related to gravity and acceleration, whereas special relativity is related to speed and time.
Why is special relativity called?
The theory was called “special” because it applies the principle of relativity only to inertial frames. Einstein developed general relativity to apply the principle generally, that is, to any frame, and that theory includes the effects of gravity.
What is relativity in simple words?
Definition of relativity 1a : the quality or state of being relative. b : something that is relative. 2 : the state of being dependent for existence on or determined in nature, value, or quality by relation to something else.
