新课标理综卷物理必考部分有两道大题:力学综合计算题,电磁学综合计算题。它们的共同特点是文字叙述量较大,涉及多个物理过程,涉及的物理模型较多且不明显,要运用较多的物理规律进行论证或计算才能求得结论,是区分度大的拉分题。以下就对这两类题分别进行分析,以帮助大家掌握正确的抓分技巧与解题策略,一、力学综合计算题[命题分析]力学综合计算题是高考的必考题,其要点是牛顿运动定律与匀变速运动规律、动能定理与机械能守恒定律的应用。
The new course physical volume part of the physical examination has two major problems: comprehensive calculation of mechanics, electromagnetics comprehensive calculation of the problem. Their common feature is the narrative volume is large, involves a number of physical processes, involving more and less physical model, to use more physical laws to prove or calculate to draw conclusions, is a large division of points question. The following two types of questions were analyzed separately to help you master the correct grasping skills and problem solving strategy, a mechanics Computation Problem [proposition analysis] Computational mechanics questions is the exam will be the exam, the key point is the Newtonian movement Law and uniform speed motion law, kinetic energy theorem and the law of conservation of mechanical energy.
