Written by teachers for teachers and students, The Physics Classroom provides a wealth of resources that meets the varied needs of both students and teachers. In special relativity, we assume that all motion is uniform (there is no acceleration or deceleration). said clock in the same system as in which the process takes place. arbitrary direction at co-ordinates t=t'=0, then the covered distance of the signal
equation (10) gives: Equation of (9) and (11) leads to the next three
