Chapter 7 System of particles and Rotational Motion
The beginning of the chapter begins with the term ‘rigid body’. System of particles and Rotational Motion is explained in detail by thinking of the bodies as being rigid. To put it another way a rigid body ideally is a body that has a perfectly fixed and unchanging shape. In other words, the distance between all the pairs of particles in a rigid body does not vary. According to the definition of a rigid body, the bodies we see in the real world are not rigid, because they deform when force is applied to them. However, when the deformations are negligible, the bodies are considered rigid.
