Chapter 5: Torque Angular Momentum and Equilibrium – Physics XI First Year Sindh Board

Physics is the study of nature, properties of matter, energy and its inter-conversion from one form to another. The subject of physics is considered as a poster child of mathematics because its roots have emerged from the field of Mathematics.


The Fifth Chapter of XI PHYSICS titled ‘Torque, Angular Momentum and Equilibrium’ is seemed as the combination of few different topics like Torque, Angular Momentum and Equilibrium. But when we will study this Chapter then you will realize that these different topics are somehow connected with each other. In the beginning of this Chapter we will study the concepts of Torque, Couple, Centre of Mass, Equilibrium, its types and Conditions of Equilibrium and then will move towards Angular Momentum and Law of Conservation of Momentum. We will also solve Examples and Problems (Numericals) to gain thorough understanding of these topics.

These concepts will be easier for you in accordance with the below mentioned features:

  • Coverage of all the topics in detail.
  • Providing topic wise assessments to Students for real time evaluation and assignments for practicing the questions.
  • Topic wise Past Papers to demonstrate the importance of each topic.
  • Study Plan for the Students to set weekly targets.
  • WhatsApp group for student queries.
