I agree with your suggestion. I also think we should not use Newton's
original work, just as most have found they can't use Feynman's text.
I wonder what would happen if we eliminated the work acceleration and
only used change in velocity, or if you wanted change in momentum. By
eliminating the word you would eliminate the task of developing a
conceptual understanding for it. I would also like to eliminate the
word displacement, since it is just the change in position. It seems to
me that students can handle vector position and vector velocity pretty
well. They can do change in position and change in velocity too, but
vector acceleration, the change of a change is just too much
for many of them to conceptualize. I'd rather just talk about the rate of
change of velocity, or of momentum. The term displacement is, in my mind,
superfluous.
