What Class 11 Physics Chapter 6 System of Particles and Rotational Motion Covers

The chapter starts with the centre of mass, builds the vector tools for rotation, and ends with rotational dynamics and angular momentum. The official NCERT sections are listed below.

Key Concepts You Will Study

Students should read the chapter with a pen and note each formula as it appears. Rotational motion mirrors linear motion, so the analogy is worth learning early.

• The centre of mass of a system and how it moves.
• The vector product and its use in torque and angular momentum.
• Torque, angular momentum and their conservation.
• Moment of inertia, the radius of gyration and the theorems on it.
• The rotational analogues of the equations of linear motion.

Why Download the NCERT Book PDF for This Chapter

The NCERT textbook is the single most important source for the CBSE exam, and most JEE and NEET questions from this chapter are built directly on its examples.

• Every Board question on moment of inertia comes from this text or its exercises.
• The worked examples show how to set up torque and angular momentum problems.
• Reading offline from the PDF lets you revise the moment-of-inertia table anywhere.

How to Use the NCERT Book PDF for System of Particles and Rotational Motion

Read the chapter once fully, then work through it again with the exercises open. A short, ordered plan keeps the linear-rotational analogy clear.

• Read each section, then match its formula to the linear-motion version.
• Solve the in-text examples before looking at the given solution.
• Attempt the back exercises, then check them against the NCERT Solutions below.
• Revise the standard moment-of-inertia values the night before the exam.
