Chapter 3: Circular and Rotational Motion | Class 11 Physics (Punjab Board New Book 2025)
Topic 3.5: Angular Momentum – Angular Momentum of a Rigid Body

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

In this lecture, we explain Angular Momentum in detail, which is one of the most important concepts of rotational mechanics.

📌 In this video you will learn:

What is Angular Momentum? (Definition & Concept)

Formula of Angular Momentum (L = r × p, L = Iω)

Angular Momentum of a Rigid Body

Difference between Angular Momentum and Linear Momentum

Relation between Torque and Angular Momentum (τ = dL/dt)

Law of Conservation of Angular Momentum (Ice Skater Example, Planetary Motion)

Applications of Angular Momentum in daily life and physics

This lecture is highly important for board exams and helps you understand advanced topics like torque, moment of inertia, rotational motion, and dynamics of rigid bodies.

📖 This lecture is part of Chapter 3: Circular and Rotational Motion from the new Class 11 Physics Book (2025) published by PECTAA.
