### What will I learn from NCERT Solutions for Class 11 Physics Chapter 7: Systems of Particles and Rotational Motion?

NCERT Solutions for Class 11 Physics Systems of Particles and Rotational Motion, explains:
1. It is necessary to determine the motion of a system’s center of mass without knowledge of the system’s internal forces. We simply need to know the external forces on the body for this.
2. 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).
3. When the total external force is zero, the total torque on a system is independent of the origin.
