研究物理的科学方法有许多,经常用到的有观察法、实验法、比较法、类比法、等效法、、极限法、转换法、控制变量法、模型法、科学推理法、图表法等.研究某些物理知识或物理规律,往往要同时用到几种研究方法.如在研究电阻的大小与哪些因素有关时,我们同时用到了观察法(观察电流表的示数)、转换法(把电阻的大小转换成电流的大小、通过研究电流的大小来得到电阻的大小)、归纳法(将分别得出的电阻与材料、长度、横截面积、温度有关的信息归纳在一起)、和 There are many scientific methods to study physics, often used are observation, experiment, comparison, analogy, equivalence, limit, conversion, control variables, model law, scientific reasoning law, chart law. To study some physical knowledge or physical laws, we often need to use several research methods at the same time.For example, when studying the factors of the resistance, we use the observation method (observing the ammeter), the conversion method The size of the current into the size of the current by the size to get the size of the resistance), inductive method (the resistance will be drawn separately with the material, length, cross-sectional area, temperature-related information together), and
