发起

Particle Dynamics makes it possible to generalize them to the motion of a system of mass points with the help of the notion of representation point. The main cases of oscillatory motion of a particle, those of motion of a particle subject to central forces as well as dynamics of the particle relative motion are analyzed in detail.

Point Kinematicsther generalized to the case of the motion of mechanical systems, whose position is described by a finite number of independent parameters. When considering curvilinear coordinates, some notions from dynamics are introduced in order to show how the differential geometry machinery can be obtained in

The results obtained for the composite motion of a particle are applied to examine the composition of motion of a rigid body. We shall consider the composition of translational motions of a rigid body and ro

System Dynamicsare extended in this chapter to the case of motion of a system consisting of . particles. The general dynamics theorems making it possible to get the integrable combinations of equations of motion of a system in certain cases are proved.

We first consider in detail the constrained motion of one material point. Next, using the concept of a representative point, the abov
