Class 11 Physics NCERT Solutions for Chapter 7 System of Particles and Rotational Motion

A rigid body is one in which the distances between its various particles do not vary despite the application of force. Only rotational motion is possible for a rigid body fixed at one point or along a line. Pure translation or a combination of translation and rotation can be achieved by a rigid body that is not fixed in any way. The following are some significant points of the System of Particles and Rotational Motion.

• It is necessary to determine the motion of a system’s centre of mass without knowledge of the system’s internal forces. We simply need to know the external forces on the body for this.
• Newton’s Second Law and Newton’s Third Law for particles are the foundations of Newton’s Second Law for finite-sized substances (or systems of particles).
• When the total external force is zero, the total torque on a system is independent of the origin.

Any genuine body that we come into contact with on a regular basis has a finite size. The idealised concept of a particle is insufficient when dealing with the motion of extended bodies (bodies of finite size). One of the best resources for Class 11 Physics is NCERT Solutions. The chapter on Particles and Rotational Motion in the CBSE Class 11 Syllabus is quite important. Students must study this chapter thoroughly in order to do well on their term – I exams. The solutions are provided below so that students can fully comprehend the concepts presented in this chapter.

The NCERT Solutions presented here are based on the CBSE Syllabus 2021-22 and have been developed by subject specialists. For all NCERT classes, Infinity Learn also provides notes, study resources, previous year question papers, sample papers, and tips & techniques.
