Adequate Theory of Oscillator: A Prelude to Verification of Classical Mechanics Part 2

In the paper, the adequate theory of oscillator is presented, being a sort of prelude to verification of the classical theory of mechanics. In the first part of the paper the principle of energy conservation was considered. This second part of the paper is to present the energetic aspects of oscillator motion. Here also an exemplary real system corresponding with the existent differential equation of oscillator is given. They are to develop the kinetics of a body in the harmonic motion, to be presented in the next Part of the work.
