Centre of Mass and Collision Class 11 Physics | Selected JEE PYQs 2021-25 | Re NEET 2026

Welcome to another high-yield Physics session for Re NEET 2026 and JEE aspirants! In this video, we are going to deeply cover and master one of the most conceptual and high-weightage topics of Class 11 Physics: "Centre of Mass and Collision". Understanding the core concepts of Centre of Mass (COM), Conservation of Linear Momentum, and various types of collisions is extremely crucial for cracking competitive exams. To help you secure maximum marks and build solid problem-solving speed, we have handpicked and solved Selected JEE Main Past Year Questions (PYQs) from the years 2021 to 2025. Solving these high-standard questions will instantly boost your confidence, expose you to the latest exam patterns, and give you an edge for the upcoming Re NEET 2026 exam! 📌 What You Will Learn in This Comprehensive Lecture: Core Concepts of Centre of Mass: Understanding the balance point for discrete particle systems and continuous rigid bodies (like semicircular rings, discs, and rods). Motion of Centre of Mass: How external forces affect the velocity and acceleration of the COM. Linear Momentum Conservation & Impulse: Analyzing system dynamics when no external force acts on it. Mastering Collisions: In-depth analysis of Elastic, Inelastic, and Perfectly Inelastic Collisions in both 1-Dimension and 2-Dimensions. Coefficient of Restitution (e): Mastering the most common equations, shortcuts, and tricks to solve tricky collision problems in seconds. Premium Question Solving: Step-by-step conceptual solutions of selected JEE PYQs (2021-2025) that are highly relevant for the Re NEET level. This video is designed to act as a complete masterclass. Whether you are studying this chapter for the first time or revising it for a quick boost, the visualization and short tricks shared in this session will help you eliminate silly mistakes and improve your accuracy.
