Heisenberg's Uncertainty Principle was originally given in terms of errors in position and this quantity.
The conservation of this quantity is due to the translational invariance of the Lagrangian, according to Noether's theorem. The De Broglie wavelength of a particle is equal to Planck's constant divided by this quantity for the particle. Heisenberg's Uncertainty Principle was originally given in terms of errors in position and this quantity. This quantity is conserved in both inelastic and elastic collisions, and the change in this quantity is equal to force times time, also known as impulse. For 10 points, name this quantity symbolized p, equal to mass times velocity.
The conservation of this quantity is due to the translational invariance of the Lagrangian, according to Noether's theorem.
