NCERT Physics Class 11 Part 1 is your gateway to classical mechanics, starting with the fundamentals of physical world and measurement. It takes you through motion in a straight line and a plane, Newton's laws of motion, work, energy, power, and the motion of rigid bodies before culminating in gravitation. Every chapter builds the conceptual scaffolding that JEE Advanced problems test extensively.

This book is non-negotiable for JEE preparation because NCERT defines the syllabus — nearly every JEE Main question is derived directly from these concepts. Read each chapter slowly, solve every example and exercise, and pay special attention to the 'Additional Exercises' at the end. Pair it with HCV or DC Pandey once your NCERT basics are rock solid.
