The questions, related to the informative features of oscillator dynamics, which succeed to be learned with the use of energy-informatics approach, are examined in this article. The spatial and kinematics parameters of simple oscillator are examined depending on energy that gives the possibility to define the dynamic parameters of oscillator - mass and rigidity. Oscillators are explored with the use of energy-informatics approach with the solution of inverse problem - the determination of mass and flexibility of oscillators' vibrations, which as separate chain lets model the medium.
