一、隐含在题给的物理现象和条件中题设的条件中必然反映若干物理现象,这些现象本身就包含了解题所需的已知条件.深刻领会物理现象的含义、产生原因和条件是获取已知条件的关键.如物体做斜抛运动时,隐含有“在最高点物体的速度方向沿水平方向”的条件;两个物体保持相对静止,隐含有“两个物体具有相同速度”的条件;两个物体刚要分离时,隐含有“两个物体间的弹力刚好为零”的条件;两个物体相距最近时,隐含有“两个物体的速度相等”的条件等等.
First, the implicit in the physical conditions of the questions and conditions set out in the conditions of inevitably reflect a number of physical phenomena, these phenomena itself contains the known conditions needed to solve the problem. Profound understanding of the meaning of the physical phenomenon, the causes and conditions Is the key to obtaining the known conditions, such as when the object is doing oblique motion, it implies that “the object is in the horizontal direction at the highest point speed”; the two objects remain relatively stationary, implying “two Objects with the same speed ”condition; two objects just to be separated, implied “ the elastic force between two objects is exactly zero ”condition; the two objects are closest, implied The speed of the object equal "condition and so on.
