✴✔1. the natural laws must preserve their forms relative to all observers in state of relative uniform motion....
✴_________"______'_____'____________✴


according to this postulate, velocity is not absolute but relative. it is a fact drawn from the failure of Michelson and Morley experiment which was performed to determine the velocity of Earth through Ether.. me

✴ 2.✔✴ the velocity of light in vacuum is independent of the velocity of observer are the velocity of the source.

✴__"__"______'______'______________✴


according to galilean transformations, this postulate is not true in fact it is confirmed experimentally that the velocity of light calculated by any method is constant. the second postulate is important in the sense that it gives a clear distinction between classical theory and Einstein theory of relativity.

Answer 2

here is your answer....................................


There are many formulations of the basic postulates of general relativity, but they really boil down to two things:

(1 )The principle of general covariance: The laws of physics are the same for all observers, regardless of their motion. This generalizes special relativity, as it also includes accelerating observers. And because “the laws of physics” includes the laws of electromagnetism, which are invariant under Lorentz-Poincare transformations but not invariant under Galilean transformations, the result of this postulate is that locally (in “sufficiently small neighborhoods”) observers are related to one another by Lorentz-Poincare transformations, just as in special relativity.


(2 ) The weak equivalence principle: Gravity is universal. It also implies that gravitational acceleration cannot be distinguished from free fall. Together with the first postulate, then, it also implies that a geometric transformation can be used to formally eliminate gravity, i.e., that gravity can be “explained” as pure geometry: this is what we mean when we say that gravity couples “universally and minimally” to matter, i.e., it determines the local geometry and nothing else.
