System of Particles and Rotational Motion
A spinning top, a rolling wheel and a balancing acrobat all involve many particles moving together. Chapter 6, System of Particles and Rotational Motion, of the NCERT Physics textbook for Class 11 analyses them. You will locate the centre of mass, relate torque with angular momentum, and apply conservation of angular momentum. Moment of inertia for common shapes, theorems of parallel and perpendicular axes, and kinematics of rolling motion connect translation with rotation in solved examples.
