一、提出问题学生问“帕斯卡原理”为何不叫“帕斯卡定理”?“牛顿定律”为何不叫“牛顿定理”?课本中的“动量定理”和“动量守恒定律”,为何一个叫做“定理”,一个叫做“定律”,是否可以都叫做“定理”或“定律”?“动能原理”为何又叫做“动能定理”?“安培定则”、“左右手定则”能否算作定理或定律?对这一系列问题,不要认为学生是在钻牛角尖、是在向老师发难,要给予其满意的答复,否则学生会对课本和老师产生怀疑,甚至会挫伤其学习积极性.二、原理、定理、定律和定则的共性与区别我们知道,物理学的理论体系是由基本概念和基
First, ask questions Why does Pascal’s principle not be called Pascal’s theorem? Why Newton’s Law is not called Newton’s Theorem? The “Momentum Theorem” and “Momentum Conservation Law” in the textbook, why is it called “theorem” , One is called “law”, whether it can be called “theorem” or “law”? “Kinetic principle” why is also called “kinetic energy theorem”? “Ampere’s rule”, “left and right hand rule” can be counted as theorem or law? On this series of questions, do not think that students are at a tip-off, is to challenge their teachers, to give them a satisfactory answer, or students have doubts about the textbooks and teachers, and even dampen their enthusiasm for learning. Second, the principle, theorem and law The commonalities and differences of the rules We know that the theoretical system of physics is composed of basic concepts and bases
