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.
关键词: 时空对称性, 参考系, 守恒定律
Abstract: 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.
Key words: spacetime symmetries, frame of reference, conservation laws
