纵观近几年高考物理的力学计算题,发现其常以“多过程”形式出现。由于这类题既可以只是直线运动问题,也可与曲线运动相结合,而且解决问题时,常要用到牛顿第二定律、动能定理、机械能守恒定律等重要规律,在新课标高考题题量减少的情况下,这样命题可以有效拓宽考查的知识面,因而成为试题改革的一个方向。多过程试题以综合方式来划分,可分为“积木式”和“混合式”。
Throughout the last few years college entrance examination physics calculation of mechanics, it often found “multi-process ” form. Because these questions can only be a linear motion problem, but also with the combination of curve motion, and solve the problem, often need to use Newton’s second law, kinetic energy theorem, law of conservation of mechanical energy and other important laws, Reduce the case, such a proposition can effectively broaden the knowledge of examination, and thus become a test reform direction. Multi-process questions to be divided into an integrated way, can be divided into “building blocks ” and “hybrid ”.
