It should be clear, by now, that there is a strong analogy between rotational motion
and standard translational motion. Indeed, each physical concept used to analyze rotational
motion has its translational concomitant. Likewise, every law of physics governing
rotational motion has a translational equivalent. The analogies between rotational
and translational motion are summarized in Table 3.
