The interesting thing about living languages is that users are permitted, perhaps even encouraged, to innovate usage of words including the invention of new words. From that standpoint I have no personal objection to the use of "deceleration" in common speech. In settings such as this one, a semi-formal science discussion group, it is a necessity that scientifically accepted verbiage be used. One can make an argument for deceleration as you have done, and make a compelling case where narrowing the definition seems appropriate. I have no nit to pick with you about "decelerate." As a matter of general usage in a science setting it doesn't have credence. You've made a narrow case that doesn't appear to have any avenue for valid dissent. Of course the acceptance of the definition of words in the science community is similar to that in definitions and acceptability of words in the general usage community albeit it is a smaller subset where the science community is concerned. Interestingly enough my mother and her generation used the expression "slow up!" I always thought that an oxymoron but in the generation before me that was well accepted in general usage, so who was I to object. So I never objected although I found it grating. Now, before someone accuses me of babbling, I retire from this discussion.
