The Realization of General Principle of Relativity in Particle Dynamics    [PDF]

ChiYi Chen

From the viewpoint of causality principle we reinvestigate the problem of dynamical relativity. We suggest that the counting of forces should also be relative so as to keep the consistency with the relative description for kinematical quantities. We propose a principle of causal consistency for the dynamical equation. Then we carry out a new general principle of dynamical relativity in a subtle way, where the dynamical equation can be exactly applied in any reference frame and the essence of inertial force can also be naturally explained. We point out that the essence of inertial forces is the real force which must be deducted in a relative counting of forces between the particle under study and the particle corresponding to the origin of the reference frame. In this way, the new formula of dynamical equation (9) is expected to replace the Newton's second law in classical mechanics since the special status for inertial reference frame is ultimately removed.
