The sum over all particles in a system of this quantity dotted with position equals the scalar virial.
The sum over all particles in a system of this quantity dotted with position equals the scalar virial. The derivative of the Lagrangian with respect to the time derivative of a generalized coordinate gives this quantity. This quantity is related to position via a Fourier transform. The magnitude of the wavevector is proportional to this quantity, since it equals Planck's constant divided by the (*) de Broglie wavelength of a matter wave. This quantity squared divided by twice the mass gives kinetic energy. Its time derivative equals force by Newton's second law. The change in this quantity equals impulse. For 10 points, all collisions conserve what quantity, which is equal to mass times velocity and denoted p?
