The fact that the operator for this and position do not commute, called the canonical commutation relation, underlies much of the weirdness of quantum mechanics.
The fact that the operator for this and position do not commute, called the canonical commutation relation, underlies much of the weirdness of quantum mechanics. This quantity is proportional to wavenumber. A term containing this variable must be added to Einstein's "E equals m c squared" equivalence to make it exactly correct. Planck's constant divided by this quantity equals a particle's de Broglie wavelength. The square of this quantity divided by twice an object's mass equals kinetic energy. Force is the time derivative of this quantity, and a change in this quantity is called an impulse. For 10 points, name this kinematic quantity equal to mass times velocity.
