Why does the movement (motion) of gas molecules become zero at absolute zero temperature?

(N/A) The average kinetic energy of gas molecules is given by the relation $K.E. = \frac{1}{2} m v_{rms}^{2} = \frac{3}{2} k_B T$,where $k_B$ is the Boltzmann constant and $T$ is the absolute temperature.
At absolute zero temperature,$T = 0 \ K$.
Substituting this into the equation,we get $\frac{1}{2} m v_{rms}^{2} = \frac{3}{2} k_B (0) = 0$.
Since the mass of the molecule $m \neq 0$,it follows that $v_{rms}^{2} = 0$,which implies $v_{rms} = 0$.
Therefore,at absolute zero temperature,the root mean square velocity of the molecules becomes zero,meaning their motion ceases.
