在近几年的中考和竞赛题中,各地悄然兴起了估算性物理试题,估算题题型灵活、知识覆盖面广、综合性强、能有效地考查同学们理论联系实际的能力.在解答估算题时,要突出主要因素,构建物理模型,挖掘隐含条件,寻找解题依据,熟悉日常生活,积累实际知识.下面分类采撷几例,供参考欣赏. In the recent examinations and contests in the past few years, there have been quietly rising presumptive physics examination questions. The questions are flexible in type, wide in knowledge, comprehensive, and capable of effectively examining the ability of students to connect theory with practice. At that time, we must highlight major factors, build physical models, explore hidden conditions, find the basis for problem solving, familiarize ourselves with daily life, and accumulate practical knowledge. The following classification picks up a few cases for reference.
