Part 1. Mechanics. Molecular physics and thermodynamics. Electricity and magnetism Part 1 examines non-relativistic (Newtonian) and relativistic mechanics, including oscillatory and wave processes, as well as molecular physics and thermodynamics, electricity and magnetism. The content of the textbook corresponds to the current level of development of physics. The material is presented in the most accessible and visual form. Depending on the tactical tasks of training, the textbook can be used for independent work of students, in classroom classes under the guidance of a teacher, as well as for correspondence and distance learning.
