摘要
艾梅·内特宣称,每一对称性对应一守恒律.本文从时空平移和空间转动对称性导出牛顿力学中能量、动量、角动量三大守恒定律.
Emmy Nother declared that to every kind of symmetry there is a corresponding conservation taw. In the present paper, the conservation laws of energy, momentum and angular momentum in Newtonian mechanics are derived from the translational and rotational spacetime symmetries.
