This book is the second volume for the study of Physics in the 3rd grade of the Orientation Group of Science Studies. Its purpose is to prepare the student in the best possible way, by presenting in detail the entire curriculum of the last two chapters of Physics in the 3rd grade that he/she will encounter during the school year.

It contains detailed theory, closed and open-ended questions, solved exercises - problems, as well as exercises and problems for solution.

- The theory is presented using the question-answer method. Where necessary, some additional information is provided, which helps clarify fine points of the theory. At the end of the theory of each chapter, there are review questions.
- The questions are structured by question type (closed type - subject 1 of national exams, and open type - subject 2 of national exams).
- The solved exercises-problems of each chapter include the methodology in basic points that the student often encounters during the solution of exercises and problems.
- The exercises for solution include basic concepts that the student must grasp before proceeding to the problems for solution, which require more complex thinking.
- In each unit, there is a detailed study proposal at two levels. The 1st level refers to basic study, while the 2nd level refers to in-depth study.
- At the end of the book, there are review problems for the entire curriculum for a final review on complex topics.

For all the questions, exercises, and problems for solution, detailed solutions are provided at the end of the book.
