Rigid body and Momentum:
Body: A body consists of a Number of particles, it has definite shape.
Rigid body: A rigid body can be defined as the combination of a large number of particles which occupy fixed position with respect to another, before and after applying a load.
A rigid body can be defined as a body, which retains its shape and size even if subjected to some external forces. In reality, nobody is perfectly rigid. But for the simplicity, we take the bodies as rigid bodies.
