NCERT Class 11 Physics – Systems of Particles and Rotational Motion
The chapter Systems of Particles and Rotational Motion in NCERT Class 11 Physics explores how forces and motion apply to multiple-particle systems and rigid bodies. It begins with the concept of the center of mass, which represents the average position of all mass points in a system. Motion of the center of mass is studied for various systems, including collisions and explosions.
The chapter also introduces rotational motion about a fixed axis, angular velocity, and angular acceleration. Key concepts like torque, moment of inertia, and rotational kinetic energy are explained with examples. Students learn to apply Newton’s laws to rotating systems and solve problems involving angular momentum and conservation of angular momentum.
By practicing NCERT examples and exercises, learners strengthen analytical and problem-solving skills, helping them excel in board exams and competitive tests like JEE and NEET.
