Noether's theorem shows that this quantity is conserved when the Lagrangian of a system possesses translational invariance, and its quantum mechanical operator is equal to negative i h-bar times the gradient operator. The de Broglie wavelength is inversely proportional to it, and the derivative of this quantity with respect to time is force. Impulse equals the change in this quantity, which is conserved by all collisions of a closed system. For 10 points, name this quantity often symbolized as p, the product of mass and velocity.
