# Important Questions For Class 11 Physics Chapter 6 System of Particles And Rotational Motion - PDF Download

Chapter 6 system of particles and rotational motion is one of the important concepts to be studied in Class 11 Physics. The system of particles and rotational motion is one of those chapters where it requires a lot of imagination and fiction for understanding the concepts. Before starting with Physics Class 11 Chapter 6 important questions, you must have a great hold on the chapter. By now students must be well known with concepts like the definition of rotational motion, rigid bodies, centre of mass system, etc.

You can boost your preparation with Class 11 Physics Chapter 6 extra questions which will enable you to solve maximum questions and with answers. The system of particles and rotational motion chapter contains several important topics that will enhance the knowledge of rigid body motion with illustrations from the objects we witness to observe in our everyday life.

Every object we see around has a finite structure, we know that rigid bodies are those in which the distance between the particles will remain constant. A rigid body or object fixed at the point will be only allowed to execute the rotational motion. A free rigid body will have either a translational motion or both translational and rotational motion.

There are some important topics that will lead to score good grades in the board exams or in any entrance examinations. Some of the key points of the chapter are as mention below:

• Knowing the motion of rigid bodies, the centre of mass of the system.

• Finding the density of the body or object depending upon the type of distribution of particles. The distribution of the particles will be either discrete or in continuous systems.

• Understanding the concept of torque and explanation and effect of torque on the rigid bodies.

• Rotational motion visualization, conservation laws, etc explained in this chapter.

Like these, we come across verious interesting topics under Chapter 6 of Class 11 Physics. For a detailed understanding of the concepts, you must practice Chapter 6 Physics Class 11 important questions. The only key to master any subject is constant determination and practising every single day. The detailed revision notes, chapter-wise materials, important questions, etc. are available on our website in the PDF form and students can download them anytime.
