文档介绍:Relativity Review
The two basic postulates of the special theory of relativity are as follows
The laws of physics must be the same for all observers moving at constant velocity with respect to one another.
The speed of light must be the same for all inertial observers, independent of their relative motion.
Relativity Review
Galilean transformations must be replaced by the Lorentz transformations

Velocity Transformation is:
Consequences
Clocks in motion relative to an observer appear to be slowed down by a factor . This is known as time dilation.
Lengths of objects in motion appear to be contracted in the direction of motion by a factor of 1/ . This is known as length contraction.
Events that are simultaneous for one observer are not simultaneous for another observer in motion relative to the first.
