This book contains more than 600 exercises and problems in Physics from the entire curriculum of the 3rd Lyceum for the subject of Physics for students in the field of science. Additionally, there are methodological comments, where necessary, especially for the more difficult problem cases.

At the end of the book, the answers to the exercises are provided. For the easier ones, only the numerical answer is given. For the more difficult ones, more detailed solutions and comments are provided to help understand the approach, and for even more difficult ones, there are general comments on how to solve similar exercises or avoid mistakes.

We tried to categorize the exercises in an efficient, understandable, and as complete as possible categorization system. We also tried to avoid extensive presentation of numerical applications and generally the extensive presentation of easy exercises, as they simply tire the student, do not offer additional knowledge and understanding, while giving a false sense of adequacy. We were particularly concerned with grading, that is, starting with easy numerical applications and gradually expanding to more difficult exercises. We tried so that each exercise has something new to offer to the student, thus expanding their understanding of the concepts of Physics and their application in the real world of physical problems, some of which are particularly demanding. We do not hide the fact that we aspired to cover as many applications as possible, as many categories of exercises as possible. It is understood that the field of Physics, even at the level of high school, appears to be limitless, but this did not discourage us, and nothing should discourage us, from the effort to internalize and conquer it.
