Basic Concepts of Mechanics

About The Book

The study of Mechanics forms the foundation of all branches of Physics. It provides the essential framework for understanding the laws governing motion, forces, and energy—concepts that are indispensable not only in classical physics but also in the development of modern theories. This book, Basic Concepts of Mechanics, has been carefully designed and written in accordance with the National Education Policy (NEP) 2020 syllabus prescribed for B.Sc. (Hons.) Physics Major students. The primary aim of this book is to present the fundamental principles of mechanics in a clear, systematic, and student-friendly manner, enabling learners to develop both a deep conceptual understanding and the analytical skills required for effective problem-solving. The topics have been arranged logically, beginning with the basic kinematical ideas and gradually progressing toward advanced concepts such as the dynamics of systems of particles, rigid body motion, and gravitation. In keeping with the spirit of the NEP framework, this text emphasizes conceptual clarity, critical thinking, and application-oriented learning rather than rote memorization. Illustrations, solved examples, and a variety of conceptual and numerical exercises have been included at the end of each chapter to reinforce comprehension and encourage self-assessment. Wherever possible, connections have been drawn between theoretical principles and their experimental or real-world applications, thereby nurturing an integrated understanding of Physics as both a conceptual and empirical science. This book will serve as a core text for undergraduate students pursuing Physics as a major subject, while also being a useful reference for those preparing for competitive examinations or seeking to strengthen their foundational understanding of the subject. The author gratefully acknowledges the invaluable contributions of teachers, colleagues, and students whose feedback and encouragement have inspired the preparation of this work. It is hoped that Basic Concepts of Mechanics will not only meet the academic requirements of the NEP syllabus but also ignite curiosity and enthusiasm for the fascinating world of Physics.
