Question

State the fundamental postulates of special theory of relativity. derive finstein's velority addition law

Answer 1

The postulates are
1.that the physics do not change for any reference frame we chose ie the physics is same every where
2.that the speed of light is constant in vacuum (that is c) and it also is invariant..

Answer 2

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
