Kinetics of a System of Particles
The most incomprehensible thing about the world is that it is at all comprehensible.
- Albert Einstein (1879–1955)
German and American Physicist
In Chapter 3 we discussed the important principles and methods used in the formulation, solution, and analysis of the motion of a single particle. In this chapter we extend the results of particle kinetics to systems consisting of two or more particles.
The first topic covered in this chapter is the center of mass of a system of particles. Using the definition of the center of mass, the linear momentum of a system of particles is defined. Then, using the definition of linear momentum, the velocity and acceleration of the center of mass of the system are ...
