This book is Concepts of Physics Part 1 by H.C. Verma, published by Bharati Bhawan. It is an English medium (अंग्रेज़ी माध्यम) book, written entirely in English (Roman script), with no Hindi content. Concepts of Physics is one of the most respected physics reference names in India, and Part 1 covers the Class 11 level portion — introduction to physics, physics and mathematics, rest and motion (kinematics), forces and Newton's laws of motion, friction, circular motion, work and energy, centre of mass, linear momentum and collision, rotational mechanics, gravitation, simple harmonic motion, fluid mechanics, some mechanical properties of matter, wave motion and waves on a string, sound waves, light waves, heat and temperature, kinetic theory of gases, laws of thermodynamics and heat transfer. The book is known for its conceptual clarity, worked-out examples, and a large set of exercises graded from short answer questions and objective questions to challenging problems with answers.
