A system's Hamiltonian differentiated with respect to a generalized version of this quantity is equal to the time derivative of position. It is described in quantum mechanics by i times h-bar times the gradient operator, and its Planck unit is equal to h bar over the Planck length, and it is equal to Planck's constant divided by a particle's de Broglie wavelength.

A system's Hamiltonian differentiated with respect to a generalized version of this quantity is equal to the time derivative of position. It is described in quantum mechanics by i times h-bar times the gradient operator, and its Planck unit is equal to h bar over the Planck length, and it is equal to Planck's constant divided by a particle's de Broglie wavelength. Via Noether's theorem, it results from translational invariance of laws of motion. Impulse describes its change in time, and force is its derivative. For 10 points, name this quantity conserved in elastic and inelastic collisions, the product of mass and velocity.
