2009年高考中的物理部分,非常强调物理模型的建构,高中物理课本中也给出较多的理想化模型和方法.如质点模型,伽利略的理想斜面实验;天体中的圆周运动模型;电场线和磁感线模型;原子结构模型等许多理想模型.在具体处理问题时,可以根据特征构建相应模型.因为模型特征越明显,解决问题 The physical part of college entrance examination in 2009 places great emphasis on the construction of physical models, and more idealized models and methods are also given in high school physics textbooks such as particle model, ideal bevel experiment in Galileo, circular motion model in celestial bodies, And magnetic induction line model; atomic structure model and many other ideal models.In the specific treatment of the problem, the corresponding model can be constructed according to the characteristics of the model features because the more obvious, to solve the problem
