Unlike kinetic energy, it is conserved in inelastic collisions, and it is usually symbolized "
The quantum mechanical operator for this quantity is negative i times h-bar times the gradient, and Planck's constant divided by this quantity gives the De Broglie wavelength. By Newton's second law, force is the time derivative of this quantity, whose change is known as the impulse. Unlike kinetic energy, it is conserved in inelastic collisions, and it is usually symbolized "p." For 10 points, name this quantity, the product of the mass and velocity of a moving body.
The quantum mechanical operator for this quantity is negative
