  The principles of creation of the mechanics of structured particles in the
frame of the Newton's laws are considered. The explanation how this mechanics
leads to the account of dissipative forces is offered. Why the motions of the
system determine by two type of symmetry: symmetry of the system and symmetry
of space and how it leads to two types of energy and forces accordingly are
discussed. How the mechanics of the structured particles leads to
thermodynamics, statistical physics and kinetics are explained.
