本文介绍了在物理教学中充分利用假设法,对运动的结果、运动过程、运动性质、运动条件进行假设,或者通过假设法增加一个运动过程,从而有效化解难点、避免复杂的计算过程,顺利分析特殊位置的特点. This paper introduces the hypothesis of making full use of the hypothetical method in physics teaching to make assumptions about the result of the movement, the course of the movement, the nature of the movement, the condition of the movement, or adding a movement through the hypothetical process so as to effectively solve the difficulty and avoid the complicated calculation process. Special location features.
