And Mr. Webster doesn't know shit about physics.  Decrease the rate
of progress relative to what?  It's all acceleration, mereley in
different directions.  When you think you are decelerating, I can
assure you you are actually accelerating in the direction opposite
your travel.  

So, yes, there is such a word as deceleration.  You get a gold star.
