| Abstract: | Most of the teaching material of mechanics and general physics,in force,look upon the law of conservation of momentum and the law of conservation of moment of momentum as the deduction of the theorem of momentum and the theorem of mement of momentum,overlook original idea of conserved quantity,is not correct. This paper gives out the exact statement. |
