一、把题目的表述“翻译”成物理条件或要求1.把题目的表述转化为物理情景有相当数量的学生读完一道题后,觉得无从下手,陷入“山穷水尽”的困境,如果在审题的过程中,把一些题目的文字表述转化为形象的物理情景,就能达到“柳暗花明”的境界.例1质量为m,电量为q的质点,在静电力作用下以恒定的速率v沿圆弧从A点运动到日点,其方向改变的角度为θ(弧度),AB弧长为 1. Translating the description of a topic into a physical condition or requirement 1. Translating the description of a topic into a physical context. After a certain number of students have read a question, they feel that they cannot start and fall into the dilemma of “failure”, if they are In the process, the textual representations of some topics are translated into the physical scenes of the image, which can achieve the realm of “little blossoms”. Example 1 Masses with mass m and power of q are driven by an electrostatic force at a constant rate v along the arc From point A to day point, the angle of change in direction is θ (rad), and the arc length of AB is
