一、弄懂物理图像的含义物理图像形象直观地反映了物理量的变化规律.对于物理图像,我们应关注以下几个方面的问题.1.横轴与纵轴所代表的物理量及其单位明确了两个坐标轴所代表的物理量,则知道了图像所反映的是哪两个物理量之间的对应关系.有些形状相同的图像,由于坐标轴所代表的物理量不同,它们反映的物理规律就截然不同,如位移—时间图像和速度—时间图像、振动图像和波动图像.另外,在识图时还要看清坐标轴上物理量所注明的单位.
First, understand the meaning of the physical image Physical image image intuitively reflects the law of the physical quantity changes. For physical images, we should pay attention to the following aspects: 1. The horizontal axis and vertical axis represent the physical quantity and its unit clearly The physical quantities represented by the two coordinate axes know which two physical quantities correspond to each other in the image. Some images with the same shape have different physical laws because the physical quantities represented by the coordinate axes are different. For example, displacement-time images and velocity-time images, vibration images, and fluctuating images. In addition, you must also be aware of the units indicated by the physical quantities on the axes when you read the map.
