[...] So through this teaching aid book (just like the corresponding book I wrote for Chemistry in the 3rd grade of Junior High School), I will try to help you fully understand all the new concepts you will learn and be able to handle the exercises.

To make it easier for you, I suggest a way for you to study the book without facing difficulties.
1. To avoid searching for what exactly you need to read each time, I divided the material into sections following the paragraphs of your textbook. Also, at the beginning of each section, you can see a summary of the topics we study.
2. Study the theory of the section carefully, which is presented in the form of questions. Through many examples and appropriate diagrams, I tried to simplify the concepts of physics so that you can fully understand them.
3. Once you are sure that you understood the theory, proceed to study the solved applications. At the beginning of each application, you will find the purpose for which it is examined. Immediately after the statement, there are comments and observations, so that you can see the difficult points of the exercise, as well as the way similar problems are approached. Try to solve the exercise by reading the statement. Use the comments that will help you. If you can't do it, see the detailed answer that follows.
