Well if you had a car going 1 mph then you slowed it down to .5 mph then .25 mph then .00005 mph... how much farther can u go? Is it possible to continuously divide up speed so that it could be say, .00000000000000000001 even?
Just a little interesting question: Is it possible to slow something down to where its impossible to go any slower and that object has to seize to be in motion?
Since there are quantums of energy, and motion is kinetic energy, there has to be a slowest speed right?
