According to the Heisenberg Uncertainty Principle, the more precisely the position of a particle is known, the less precisely its momentum (and thus velocity, for a given mass) can be known, and vice versa. Therefore, if the accuracy in measuring velocity increases, the accuracy in measuring position must decrease.
