A form of this quantity is the associated Noether (“NURR-turr”) current when the Lagrangian (-5[1])does not depend on a given coordinate. This quantity’s “conjugate” (10[1])form equals the derivative of the Lagrangian (10[1])with respect (-5[1])to generalized velocity (10[2])and is related (10[2])to q and q-dot (10[1])in Hamilton’s equations. (10[1])Position (10[1])and the generalized (10[2])form of this (10[2])quantity (10[3])are the (10[1]-5[1])usual coordinates (10[1])of (10[1])phase (10[1])space. (10[6]-5[1])The (-5[1])square (10[1])of this quantity’s (10[2]-5[1])“linear” form (10[1])divided by two times (10[2])mass (10[3]-5[2])equals (-5[1])kinetic (10[2]-5[3])energy. (10[10]-5[7])In the general (10[1])statement (10[1]-5[3])of (-5[2])Newton’s (10[1]-5[3])third (-5[3])law, (10[2]-5[4])force (-5[1])equals (-5[2])the time (10[2])derivative (0[1]-5[4])of this quantity, (10[2]-5[6])which is (-5[1])conserved (-5[2])in all (10[1])collisions. (10[3]0[1]-5[2])For 10 (10[1])points, (10[2])name (10[1])this (10[1])quantity equal to mass times (10[1]-5[1])velocity. (10[5])■END■ (10[34]0[15])
