摘要
现如今高考试题对物理模型建构的考查越来越多,圆周运动作为过程模型中的考查重点,因此在教学中要尤其注重圆周运动模型建构的应用。将普通模型建构方法应用到圆周运动的模型建构中,使学生掌握基本的模型建构方法。举出圆锥摆、火车转弯、水平旋转圆台的例子,示范圆周运动的模型建构方法,展示模型建构在课堂中应用的方法和注意事项。通过经典旋转陶罐例题的训练,提高学生应用物理模型建构方法解决复杂问题的能力。
Nowadays,the college entrance examination has more and more investigations on the construction of physical models,and circular motion is the focus of investigation in the process model,and special attention should be paid to the application of model construction in teaching.Apply the general model construction method to the model construction of circular motion,can help students can master the basic model construction method.Examples of conical pendulums,train turns,and horizontal rotation tables are given to demonstrate the model construction method of circular motion,and the methods and precautions applied in the classroom are demonstrated.Through the training of classical rotating clay pot examples,students'ability to apply physical model construction methods to solve complex problems is improved.
