Then, having shown the structure of classical particle mechanics, the author introduces Suppes-Sneed approach. In what follows, relying the view accepted in this article, the author mentions its deficiencies; and poses the question "How can comparability of scientific theories be made possible through redefining them?" Finally, the main structure of particle mechanics together with its associated models is introduced.
