This book presents in detail the first two units ("Curvilinear Motions: Horizontal Projectile, Circular Motion" and "Conservation of Momentum") of the Physics Orientation for the 11th grade.

Each chapter includes:

• Theory in the form of questions, so that the student can focus on the specific topic.
• Observations that help the student understand key points and avoid potential "traps" that could lead to incorrect solutions. These observations will be particularly helpful for the student's review for the June exams.
• Basic exercises with exemplary solutions. During the solving process, "key points" are presented in a frame that help the student draw useful conclusions which can be used for solving exercises.
• Questions covering the entire spectrum of the syllabus, aiding in a better understanding of the theory.
• Exercises and problems to solve, whose quantity and variety ensure the student's proper preparation.
•  Evaluation criteria, for the student to check their knowledge.

After the development of the syllabus chapters, tables with the most important formulas are provided, as well as two review evaluation criteria.

At the end of the book, there are answers to the questions and solutions to the exercises, problems, and evaluation criteria.

I thank all my colleagues and students whose observations helped in the writing of this book, and I look forward to their suggestions for its further improvement.
