在oxy坐标中,y=kx+b表示的是一条直线,如果我们对其中的x、y、k、b以及图线下的面积S均赋于一定的物理内容,则此直线也就具有一定的物理意义。例如v=at+v_0表示的是在匀变速直线运动中速度和时间的关系。eU=hv-w表示的是光电效应的规律。U=rI+ε表示的是在全电路中路端电压和电路中电流的关系(全电路欧姆定律)……等等。在物理教学中应用这些图象来分析讨论有关物理问题,不仅可以加深对基本物理概念、物理规律的理解,而且也将有助于数理结合能力的提高和
In oxy coordinates, y=kx+b represents a straight line. If we assign a certain physical content to x, y, k, b and the area S under the graph, the straight line will have certain The physical meaning. For example, v=at+v_0 represents the relationship between speed and time in a linear motion with constant speed. eU=hv-w represents the law of the photoelectric effect. U = rI + ε represents the relationship between the circuit voltage in the circuit and the current in the circuit (all-circuit Ohm’s law) ... and so on. Applying these images in physics teaching to analyze and discuss relevant physical issues can not only deepen the understanding of basic physical concepts and physical laws, but also help to improve the combination of mathematical and physical skills.
