Thanks a lot for making it clear to me

[SIZE="3"]A rod moves along x-axis with speed u and has length L relative to Inertial Frame S. What is its length L' relative to the other inertial S' that moves with speed v with respect to S. I know the famous length contraction formula L=L' * sqrt(1-square(v/c)) but I confuse how to...

I couldn't get the sense of this sentence. [ how would you calculate the proper time along a world-line (t, x(t)) where dx/dt isn't constant? ]

I am sorry but could u please explain your point in a bit more detail. I couldn't get your point completely. :confused: thanks

thanks... actually i am novice to SR. well ...I think straight worldline in space-time diagram represents linear motion with constant speed. and moving clocks run slow. but what happen when clocks are taken from event 1 to event 2 in a fashion that make curveved worldline? i.e. when clocks...

Ideal clocks are taken from event A to event B along various worldlines. then that the longest proper time for the trip is indicated by that clock whcih follows the straight worldline. How it can be showed. thanks

a particle moves close to the speed of light, say u, around a circular path. what is acceleration according to particle's own reference frame?

While solving the problem from Rindler 2nd ed. book, I just stuck on the problem 3.24. [SIZE="3"]A certain piece of elastic breaks when it is stretched to twice its length. At time t=0, all points of it are accelerated longitudinally with constant proper Acceleration alpha, from rest in the...
