物理习题是实际物理问题与现象的科学简化、科学抽象和物理化模型。习题解答,是对解决问题的一种模拟,是中学物理教学中培养能力、开发智力的重要途径和手段。一、物理习题的作用(1)巩固深化物理概念和规律。学生对于学习的新知识,理解只是表面的和片面的,并不能完全理解它们的实质和意义。只有通过适当的具体习题的解答、与广泛的实际材料结合,从多方面
Physical exercises are scientific simplifications, scientific abstractions, and physics models of actual physical problems and phenomena. Answers to exercises are a simulation of problem solving and are an important means and means of cultivating ability and developing intelligence in middle school physics teaching. First, the role of physical exercises (1) Consolidate the deepening of physical concepts and laws. Students’ understanding of new knowledge of learning is superficial and one-sided, and they cannot fully understand their essence and meaning. Only through the answers to appropriate concrete exercises, combined with a wide range of practical materials, from many aspects
