学习物理,离不开数学知识.但在运用数学知识分析物理问题时, 丁不能只用数学的观点去处理,还应注意物理自身的规律,否则会影响你正确解题. 例如,我们在分析和解答物理题时,需要用一些符号来表示各个物理量.有些同学往往用数学上的x、y等符号来表示,而忽视了在物理中各个物理量都有其特定的或惯用的字母符号(如速度用v、密度用ρ表示等),这样做 Learning physics is inseparable from mathematics knowledge. But when using mathematical knowledge to analyze physics problems, Ding cannot use only the mathematical point of view to deal with it, but also pay attention to the laws of physics itself, otherwise it will affect you to solve problems correctly. For example, we are analyzing When solving physical problems, some symbols are needed to represent each physical quantity. Some classmates use mathematical symbols such as x, y, etc., and ignore that each physical quantity in physics has its own specific or customary alphabetic symbol (eg, Velocity is expressed in v, density in ρ, etc.)
