Moment of Inertia | Class 11 Physics Chapter 3 | Pectaa Punjab Board 2025
Chapter 3: Circular and Rotational Motion | Physics Class 11 New Book (2025)
Topic 3.4: Moment of Inertia | Subtopic: Moment of Inertia of Rigid Body

Welcome to the official 1st Year Physics Lecture Series for the New PECTAA Book (Punjab Board 2025).

In this video, you’ll learn:
🔹 What is Moment of Inertia (I)?
🔹 Concept of rotational inertia – how mass resists angular acceleration
🔹 Derivation and formula of moment of inertia for rigid bodies
🔹 Dependence of moment of inertia on mass distribution
🔹 Examples: Moment of inertia of solid sphere, disc, rod, ring
🔹 SI unit and dimensional formula of moment of inertia
🔹 Difference between mass and moment of inertia
🔹 Relation with torque and Newton's second law for rotation

💡 This lecture is very important for your board exam preparation and numerical questions in Chapter 3.

📚 This topic is part of the Circular and Rotational Motion chapter from the new 11th Class Physics Book 2025, designed by PECTAA (Punjab Curriculum & Textbook Authority).
