在中学物理中 ,许多物理规律、定理、公式等都可以用坐标图线来表示。图线表示的结果准确性高、包容量大 ,而且形象直观 ,既简化计算过程 ,又便于分析实验误差 ,给教与学带来极大方便。因此 ,正确理解各种坐标图线所表达的相应规律及现象的物理意义 ,在解决问题时才能做到心中
In the middle school physics, many physical laws, theorems, formulas, etc. can be represented by coordinate graph lines. The graph line shows the high accuracy, large package capacity, and intuitive image, which not only simplifies the calculation process, but also facilitates the analysis of experimental errors, bringing great convenience to teaching and learning. Therefore, the correct understanding of the corresponding laws and the physical meaning of the phenomena expressed in various coordinate graph lines can only be achieved when the problems are solved.
