A basic postulate of Einstein's theory of relativity is:
A)moving clocks run more slowly than when they are at rest

D)the laws of physics must be the same for observers moving with uniform velocity relative to each other
E)everything is relative

Question

Quizplus · Accepted Answer

The postulate that the laws of physics must be the same for observers moving with uniform velocity relative to each other is known as the principle of relativity and is a fundamental basis for Einstein's theory of relativity. Options A and B are consequences of relativity, rather than postulates, and option C is a property of light that has been known since the early 20th century. Option E, while a popular phrase, is too vague and does not capture the specific postulate of relativity.
