This book was written with the desire to be an important aid for the study of physics in the first year of high school. Students who enter high school from middle school are called upon to face exercises and problems of greater difficulty in the subject of physics than those they encountered up to that point in middle school. In this particular book, there are many solved examples, as well as many exercises and problems that aim to train the student in dealing with the most difficult concepts they will find in this subject.
The book contains:
- Theory, in the form of question and answer.
- Multiple choice questions, true-false questions, matching questions, and fill in the blank questions, to check the theory.
- Open-ended questions (essays), where the student must develop their thinking in their notebook (justify their answer).
- Solved examples, written in a detailed way, so that the student can follow the solution with great ease.
- Exercises and problems to solve, which are of varying difficulty.
- Difficult problems, which require a great effort to solve.
- Review problems for each chapter.
For all the questions, exercises, and problems to solve, there are detailed solutions at the end of the book (blue pages). Also included are the answers-solutions to the questions and exercises in the textbook.
Finally, I would like to express my warm thanks to my excellent physics colleagues Vasilis Istapoulos from Athens and Kostas Psylakos from Chalkida, who read the originals and with their great experience in teaching physics made accurate observations and remarks.
