Document Summary

Impulse and momentum v - centre of mass. The world is a very complicated place, as you know, with enormously complicated processes going on. In this course, when we analyze the motion of a tossed baseball, we don"t consider the motion of each individual atom in the baseball, but we rather treat the baseball as a whole. The motion of each individual atom in the baseball is quite complicated, and analyzing the motions of all of the atoms in a baseball is quite a long way beyond our capability. There are too many atoms, their motions are too complex, and we have no way of measuring all of them to see if our analysis would be correct, if it were even possible to carry out such an analysis. The atoms are vibrating, jiggling, etc. , in an extremely complex way. Nevertheless, all of the complications are not very important, in a way.
