解决力学实验问题的关键有三点,首先是应该从基本实验原理、实验器材、操作步骤、实验结论的表达方式等方面着手,加强对实验的一般思想及方法的理解与运用.其次是掌握常规实验的数据处理方法,作图法应用较多,用作图法处理数据的优点是直观、简便,能有效地减少偶然误差对测量结果的影响.由图线的斜率、截距、所包围面积和图线的交点等可以研究物理量之间的变化及其关系,对此应多加训练,熟练掌握.再次是能将课本中分组实验和演示实验的实验原理、实验方法迁移到新的背景中,深刻理解物理概念和规律,并能灵活运用.下面就
The key to solve the problem of mechanics experiment is three points, first of all should be from the basic experimental principles, experimental equipment, operational steps, the experimental conclusions of the expression and so on, to strengthen the general idea of the experiment and the method of understanding and use.Secondly, to master the routine experiment The data processing methods are widely used in the mapping method, and the advantages of using the method as the data processing method are intuitive and simple, and can effectively reduce the influence of accidental errors on the measurement results. The slope, intercept, The intersection of the graph line and so on can study the change of the physical quantity and its relation, to this should should increase the training, proficiently.Third is to be able to textbook group experiment demonstration experiment demonstration principle, the experiment method migration to the new background, deep Understand the concepts and laws of physics and apply them flexibly
