A system of particles means a group of particles inter-related. The equations for a system of particles can be readily used to develop those for a rigid body. One new but very important concept introduced with a system of particles is the center of mass. The following quantities are covered in this section:
The equations for linear motion variables such as CM and momentum are generally very simple. But those for the angular motion variables become bit more complex than those for a particle. These equations will be further developed in the Rigid Body Dynamics section. |
