浅谈“动量定理”的广泛意义丁宪杰程学武（安徽省怀宁二中，２４６１００）动量定理是物理学中的一个重要推论，是解决动力学问题的基本手段之一．动量定理除了可以解决一些比较简单的、与时间相关的单个物体的动量变化问题之外，还可以解决过程比较复杂，以及受变力作用...
On the Extensive Significance of the “Momentum Theorem” Ding Xianjie Cheng Xuewu (Huining II, Anhui Province, 246100) The momentum theorem is an important inference in physics and is one of the basic means to solve the dynamic problem. The momentum theorem can not only solve the problem of momentum change of some simple and time-dependent single objects, but also can solve the complex process and the effect of variable force...
