摘要
本文从实际生活中的相同位移下节约时间的运动学问题出发,抽象出物理模型,应用作差、作商以及图像法建立物理量的等量关系,进行科学推理,解决现实中提高效率的问题。
This paper starts from the kinematics problem of saving time under the same displacement in real life, abstracts the physical model,applies the difference,the operator and the image method to establish the equivalent relationship of physical quantity,carries on the scientific reasoning,and solves the problem of improving the efficiency in reality.
