It is explained by Heisenberg's uncertainty principle, it is impossible to calculate simultaneously both the position and the momentum of the particle.
Let x and p be the uncertainty in the concurrently measurement of the position and momentum of the particle, then ; where and h = 6.63 × 10-34 J-s is the Planck's constant.
