As we discussed in Chapter 10, physics includes the study of rotation.
Arguably, the most important application of that physics is in the rolling motion
of wheels

v = + ( 80 km/h ) (1000 m/km)(1 h/3600 s) = (+22 m s)i,

1. The problem asks us to assume vcom and are constant. For consistency of units, we
write

As we have discussed, one focus of physics is motion.
However, so far we have examined only the motion of translation, in
which an object moves along a straight or curved line, as in Fig. 10-1a.
