When we compare two velocities or
decide when velocity is increasing or decreasing (a comparison), aren't
we really comparing "speeds"? I try to stress this to my students, but
it is easy to fall back to the standard "calculus rules" when it comes
to determining maxima, inc/dec intervals, etc. Am I wrong in my
thinking? How do you approach this subject
