Solid Bodies An ordinary object, such as a baseball bat, contains so many particles (atoms) that we can best treat it as a continuous distribution of matter. The particles then become differential mass elements , the sums of  become integrals. and the coordinates of the center of mass are defined as You can bypass one or more of …
