Engineering Physics Annotation << Back MACH-POINCARE RELATIVITY PRINCIPLE AND DYNAMIC NON INERTIAL SYSTEM’S B.S. SADYKOV The physical nature of inertia is explored. Based on Mach-Poincare principle, offer hypothesis of the induction nature of inertia and theory, which extend allows the principle of relativity to the non-inertial reference systems, united system of Electrodynamics and Gravidynamics Equation. Received formula for transformation of Coordinates in Non-Inertial Systems. The theory eliminate shortcoming of Newtonian mechanics and Special Theory of Relativity, and predict new effects. Key words: inertia, gravitation, relativity, inertial field. Contacts: E-mail: beh-7@rambler.ru Pp. 03-10.
