Answer to Question #204041 in Mechanics | Relativity for Xavier

Question

State Einstein's postulates of relativity

Answer 1

Answer

• Einstein has made 2 postulates in the journey of defining special relativity.

• The first one is,

"In all inertial frames of reference, the laws of physics remains the same"

• This explains that the laws of physics are not seen differently from frame (inertial) to frame(inertial).

• The second one explains that the behavior of light in inertial frames of reference. Its velocity is invariant of the direction it travels & has one fixed magnitude of course in a vacuum.

"Light, in a vacuum travels at the same speed of c in any direction in all inertial frames of

reference"
