Chapter 26 – Relativity
... Postulate 1: The laws of physics are the same in all inertial reference frames (the principle of relativity). An inertial reference frame is one in which no accelerations are observed in the absence of external forces. (Recall Newton’s first law). ...

... say that the speed should be the sum of the two speeds, or 1.50c. This answer must be incorrect because it contradicts the assertion that no material object can travel faster than the speed of light. • Let two frames or reference be labelled b and d, and suppose that frame d is moving at velocity vd ...

The simplest and the most commonly used frame of reference is the Cartesian system of coordinates with observer at the origin. It is not essential that the position of observer should c ...

... Time dilation in the decay of muons produced by cosmic rays at the top of the atmosphere have lifetimes of 2 s, so should travel only a few hundred metres before decaying. Their speeds are close to c, so most of them travel through many tens of km of atmosphere due to time dilation. Michelson-Morle ...

Moving from Newton to Einstein
... If you ask a random collection of first year students, “What do you know about relativity?” the answers might be: “All is relative?” “It all depends on your frame of reference.” “You will never measure an absolute velocity unless you look into space.” “Wasn’t it invented by the same guy that gave us ...

... This is the velocity with respect to the car, but what about the velocity with respect to the sidewalk? Would it be c+v ? That would agree with our common sense, but not with Maxwell’s Equations. Maxwell’s Equations state that the speed of light is c and only c, but for which reference frame does it ...

It means that if two observers performed an experiment in 2 different reference frames moving with constant relative velocity ( inertial frames ) they will get exactly the same results. ...
