各省市历年物理中考实验题中,如何测物质密度、测电阻、测电功率等实验的比例很大,涉及测其他物理量的题很少。研究近一、两年的物理中考实验命题,发现有一种新的趋势即如何用非常规的方法测上述三个物理量(密度、电阻、电功率)之外的其他物理量,现归纳、列举如下。 In the provinces and cities in the physics examination subjects over the years, how to measure the density of the material, measure the resistance, measure the power and other experiments is very large, and there are few questions involving the measurement of other physical quantities. Studying the physics entrance exam experiment proposition in the past one or two years, we found that there is a new trend that is how to use unconventional methods to measure other physical quantities beyond the above three physical quantities (density, resistance, and electric power), which are summarized and listed below.
