Systems of point masses
摘要
In this chapter we deal with the kinematics and kinetics of systems of point masses, i.e. systems that are composed of a number of point masses that are connected to each other by certain types of coupling. In addition to the law of motion for the center of mass, with the help of which we can describe the motions of such systems of point masses, we also consider the impulse law and angular momentum theorem as well as the principle of work and energy and the law of conservtion of energy for systems of point masses.
