  Quantizing the transfer of energy and momentum between interacting particles,
we obtain a quantum impulse equation and relations that the corresponding
mechanical power, force and torque satisfy. In addition to the energy-frequency
and momentum-wavelength relations, we introduce the power-frequency and
force-wavelength analogs, respectively. Further, we obtain an operator
representation for the mechanical power and impact force in the position space
and discuss their correspondence with the relevant momentum operator. The
position representation of the torque operator and its relation to the orbital
angular momentum operator is also considered. The results are grounded by the
presence of a constant that appears as fundamental as the Planck's constant to
all obtained relations.
