从初中物理向高中物理过渡,学生明显感觉到以前接触的很多物理量有了方向,并且不再是单纯的正反两个方向,而是三百六十度各个方向都有可能性。这样一来,矢量分析法则的熟练掌握就显得尤为重要。在人教版高中物理中,虽然一开始就学习了运动学,但矢量性仅表现为正负方向,真正的矢量分析法则是在研究力的合成与分解中得出并应 From junior high school physics to high school physics transition, students obviously felt a lot of physical contact with the direction of the past, and is no longer a simple positive and negative directions, but three hundred and sixty degrees in all directions are possible. As a result, the master of vector analysis rules is particularly important. In PEP physics, though learning kinematics from the very beginning, the vectoriality is only positive and negative. The true vector analysis rule is derived from the synthesis and decomposition of the research force
