Round 8: Tossup 19

A form of this quantity is the associated Noether (“NURR-turr”) current when the Lagrangian does not depend on a given coordinate. This quantity’s “conjugate” form equals the derivative of the Lagrangian with respect to generalized velocity and is related to q and q-dot in Hamilton’s equations. (10[1])Position and the generalized (10[1])form of this quantity are the usual coordinates of (10[1])phase space. The square of this quantity’s “linear” form divided by two times (10[1])mass (10[1])equals kinetic energy. (10[1]-5[1])In the general statement of (-5[1])Newton’s third law, force equals the time derivative (-5[1])of this quantity, (10[1])which is conserved (-5[1])in all collisions. (-5[1])For 10 points, name this quantity equal to mass times velocity. ■END■ (10[2]0[2])
