Momentum

Chapter

In this chapter we begin our study of more realistic systems in which the objects are no longer point particles but have extension in space. Up until now we’ve generally limited ourselves to the dynamics of point masses, first in one dimension and then generalized to two and three dimensions. Indeed, not all of the problems we studied were limited to point masses, but the object’s size and shape were not relevant in the problem and so were not considered. For such objects we’ve learned how to describe and predict translational motion using Newton’s laws, some of the complications due to frictional forces, and the important concept of energy. In general we can divide the motion of real extended bodies into two parts: translational motion, described by following a particular average coordinate of the object, known as its center of mass as it moves about, and all other motions with respect to this point. This chapter focuses on translational motion of systems, or collections of objects,...
