**Abstract:**

Postulating the absolute speed of light was accompanied by serious implications highlighted mathematically by a set of transformations derived by H. A. Lorentz based on the classical electrodynamics theory. As a result, the Newtonian absolute space-time geometry had been modified by special relativity to be in agreement with the mathematical expressions of Lorentz transformations. Furthermore, all dynamical alterations in the physical quantities were interpreted to be as a result of the kinematical alterations imposed to these quantities. For example, the inertia of the moving body increases “apparently” compared to its inertia at rest. This inertia increase - according to special relativity - is not an intrinsic property for the moving body, but rather, it is a consequence of the time dilation encountered by this moving body, which implies that the kinematical part (time dilation) is acting as the cause, whereas the dynamical part (inertia increase) is acting as the effect.
