About the book

This book is as per the revised syllabus of Engineering Physics-I (NAS-101), Engineering Physics-II (NAS-201) and Practical (NAS-151/251) of Uttar Pradesh Technical University (UPTU), Lucknow. Basic principles and applications of Engineering Physics are explained a simple, lucid and systematic manner. Beginners will understand complex ideas easily through appropriate examples, neatly drawn diagrams, tables wherever required, etc. Accompanying LAB MANUAL provides detailed theory, method, observation table and question and answer for viva-voce. It provides complete information on all experiments prescribed as per UPTU syllabus.Chapter 1 Relativistic Mechanics 1.1 Introduction 1.2 Some Important Terms 1.3 Frame of Reference 1.4 Earth:
