Question

what is the fundamental postulate of theory of relativity?

Answer 1

$\huge \bf \red{ ANSWER}$

THE FUNDAMENTAL POSTULATE OF THEORY OF RELATIVITY IS

▶THE LAWS OF SCIENCE SHOULD BE SAME FOR ALL FREELY MOVING OBSERVERS, NO MATTER WHAT IS THIER SPEED.

THIS WAS TRUE FOR NEWTON'S LAWS LAWS OF MITION, BUT NOW THE IDEA WAS EXTENDED TO INCLUDE MAXWELL'S THEORY AND THE SPEED OF LIGHT.

ALL OBSERVERS SHOULD MEASURE THE SAME SPEED OF LIGHT, NO MATTER HOW FAST THEY ARE MOVING. THIS SIMPLE IDEA HAS SOME REMARKABLE CONSEQUENCES. PERHAPS THE BEST KNOWN WAS THE EQUVALANCE OF MASS AND ENERGY SUMMED UP IN EINSTEIN'S FAMOUS EQUATION E=MC^2 .

Answer 2

$\huge\mathfrak\red{Answer:-}$

• The Relativity Postulate

The laws of physics are in the same in every interial reference frame.

• The speed of light postulate

The speed of light in vacuum measured, in any interial reference frame always has the same value of c, no matter how fast the source of light and the observer are moving relative to each other.
