13.3.2 Motions of Particles

The Newton-Euler model is described in terms of particles. Each
*particle* is considered as a point that has an associated mass
. Forces may act on any particle. The motion of a rigid body,
covered in Section 13.3.3, is actually determined by
modeling the body as a collection of particles that are stuck
together. Therefore, it is helpful to first understand how particles
behave.
