The book has been written according to the instructions of the Ministry of Education for the teaching of Physics in the 2nd grade of High School, in the Science and Technology direction.

With the aim of presenting the entire theory in an understandable way and at the same time solving any doubts that arise in a class as a whole, I hope that this book fully meets the needs of students, responding to the requirements of this specific subject.

The educational aid, structured in sections, includes:
- Key points of the theory
- Complete theory in the form of questions - answers
- Exercises solved in an exemplary way
- Evaluation Question Bank (multiple choice questions, true-false, completion, matching)
- Exercises for solution, distributed in levels of difficulty
- Evaluation criteria per section
- Review exercises
- Review Evaluation Criteria (combined)
- Answers to questions and solutions to exercises and problems in the textbook

Also, in order to assist the work of fellow teachers, I would like to point out that the answers of the Evaluation Question Bank, the Exercises, and the Evaluation Criteria (per section - review) are available for free on the website of Ellinoedotiki www.ellinoedotiki.gr
