“隔离法”和“整体法”在初中物理教学中 ,教材中虽然没有介绍和要求。但如果在实际学习中作适当的了解 ,对培养思维能力 ,掌握力学的解题方法和技巧 ,都有很大的促进作用。特别是“隔离法”和“整体法”优化 ,解“连接体”竞赛题 ,更能体现它的魅力。1　方法简介 :在解力学问 “Isolation Law” and “the whole law” in junior high school physics teaching, although there is no introduction and request textbooks. However, proper understanding in practical learning can greatly promote the cultivation of thinking skills and the mastery of mechanical problem solving methods and techniques. In particular, the “isolation law” and the “overall law” optimization, solution “connector” contest title, better reflect its charm. 1 Method Description: Learning in solution
