Commutation and the resulting uncertainty relations are studied. ``Quantum mechanical q-Hamiltonian'' of the motion over the quantum plane is derived and the solution of the Schroedinger equation for the q-semiclassical motion governed by the expectation value of that Hamiltonian is solved.Latex, 17 pagesQuantum AlgebraUncertainty Relations and Wave Packets on the Quantum Planetext
