Introduction
Mechanics is a branch of physics that studies the patterns of mechanical movement and the reasons that cause or change this movement. Mechanical motion exists in all higher and more complex forms of motion of matter (chemical, biological, etc.). These forms of movement are studied by other sciences (chemistry, biology, etc.).
In the main textbooks questions on the study of mechanical motion are presented in detail, often with cumbersome mathematical calculations, which significantly complicates the independent work of students.
The methodological instructions provide the working program of the “Mechanics” section, definitions of physical concepts, briefly outline the basic physical laws and regularities of classical mechanics, and record these laws in mathematical form.
The “Mechanics” section examines the kinematics and dynamics of a material point, the kinematics and dynamics of rotation of a rigid body around a fixed axis, and conservation laws.
To study the “Mechanics” section, you need knowledge of mathematics: elements of vector algebra (projection of a vector onto an axis, scalar and vector products, etc.), differential and integral calculus (calculation of the simplest derivatives and finding antiderivatives).
Due to limitations in the volume of the publication, the guidelines do not reflect experimental material.
These guidelines will help students in independently studying the mechanics course during the examination period.

Physics is one of the basic sciences of natural science. The study of physics at school begins in the 7th grade and continues until the end of school. By this time, schoolchildren should already have developed the proper mathematical apparatus necessary for studying a physics course.
- The school curriculum in physics consists of several large sections: mechanics, electrodynamics, oscillations and waves, optics, the quantum physics, molecular physics and thermal phenomena.
School physics topics
In the 7th grade There is a superficial familiarization and introduction to the physics course. Basic physical concepts are considered, the structure of substances is studied, as well as the pressure force with which various substances affect others. In addition, the laws of Pascal and Archimedes are studied.
In 8th grade various physical phenomena are studied. Initial information is given about the magnetic field and the phenomena in which it occurs. Direct electric current and the basic laws of optics are studied. The various aggregate states of matter and the processes that occur during the transition of a substance from one state to another are analyzed separately.
9th grade is devoted to the basic laws of motion of bodies and their interaction with each other. The basic concepts of mechanical vibrations and waves are considered. The topic of sound and sound waves is discussed separately. The fundamentals of electromagnetic field theory and electromagnetic waves. In addition, there is an acquaintance with the elements nuclear physics and the structure of the atom and the atomic nucleus is studied.
In 10th grade An in-depth study of mechanics (kinematics and dynamics) and conservation laws begins. The main types are considered mechanical forces. There is an in-depth study of thermal phenomena, molecular kinetic theory and the basic laws of thermodynamics are studied. The basics of electrodynamics are repeated and systematized: electrostatics, the laws of constant electric current and electric current in various media.

GENERAL PHYSICS COURSE. T.I MECHANICS
The main content of the proposed course is an extended presentation of lectures on physics, which the author read for many years (since 1956) at the Moscow Institute of Physics and Technology. Overall plan The lecture course, as well as the basic approach to presenting fundamental issues in physics, changed little over the years. However, every year the course was updated to include new private questions and examples. Many previously considered issues were excluded. This was done not for reasons of principle, but due to lack of time.
This course includes almost all the issues presented in the lectures in different years. Questions that were not discussed in the lectures were also included. They occupy about 10-15% of the text. In addition, many problems are included with answers or detailed solutions. All this material can be of benefit to students when in-depth study physicists and teachers during seminar classes. It, the author hopes, will contribute to the development of students' physical thinking skills and the ability to independently pose and solve fundamental questions and specific physical problems, which is the main goal of the proposed manual. Of course, not all of this material is required. For the convenience of the reader, the main questions are printed in large font, all the rest are printed in small font.
