Special Relativity and Lorentz Transformations

A reference frame where Newton's laws are valid and a body not subjected to net external forces moves in rectilinear motion at constant velocity.

If Newton's laws are valid in one inertial reference frame, then they are valid in another inertial reference frame moving at a uniform velocity relative to the first system.

K' has a constant relative velocity in the x-direction with respect to K, and time (t) is a fundamental invariant for all observers.
