Mechanics of Uniform Motion of a Rigid Body

This article analyzes the force parameters of the processes of solid body motion when external and internal forces act. On the basis of the analysis of the mechanics of the process of uniform motion of a rigid body, the authors found necessary conditions for uniform motion of it or its static equilibrium when balanced external forces act. A uniform motion of a rigid body under the action of balanced external forces of motion and resistance to motion is realized when these forces have independent sources of energy that interact with each other due to the displacement of a solid body. In this case, the energy source of the force of motion expends a certain amount of energy and the source of resistance force accumulates the same amount of mechanical energy by transferring the mechanical energy from the source of energy of the driving force to the source of the energy of the resistance force.
