The Motion of Celestial Bodies Complies with Conservation of Angular Kinetic Energy

Abstract

Application of force accompany with energy consumption is the basic common sense. Based on this common sense, Newtonian mechanics system is studied according to energy transformation and conservation law. A concept of dissipation work is proposed and a calculation formula of dissipation work is derived. Meanwhile, thermal effect of force is obtained through inference, kinetic energy theorem is amended, and supplements of angular kinetic energy theorem and the law of conservation of angular kinetic energy are made. Through the above research, celestial body movement is found to comply with conservation of angular kinetic energy, rather than the conservation of angular momentum or the so-called conservation of mechanical energy. Also, the potential energy, which is superfluous in Newtonian mechanics, is found not to be energy.  Therefore, the unity of conservative forces and non-conservative forces is realized. The revised Newtonian mechanics will have a profound influence on subjects and relative research fields of physics, astronomy and astronautics.
