A brief theory, problems with solutions and tests in mechanics, molecular physics and thermodynamics are given . The manual consists of two sections corresponding to the physics course program for technical universities. At the beginning of each chapter, the theoretical foundations, basic definitions and formulas are set out. Many problems of varying degrees of complexity with solutions and tasks for independent solution. are given. Methods of solving tests are outlined, and tests are given to test the assimilation of theoretical material. The application considers the possibility of designing a space elevator. The textbook is intended for students studying in the areas of "System Analysis and Management" and "Innovation", as well as teachers of universities and colleges, can be useful for applicants preparing for admission to technical universities. ;Grif:Recommended by the UMO for university polytechnic education as a teaching aid for university students studying in the direction of bachelors training "System Analysis and Management" and the direction of bachelors training "Innovation"
