科里奥利力可以应用在许多现象的解释上,比如傅科摆、信风与季风、热带气旋、地球自转对分子光谱的影响等。但在大学物理课堂中,科里奥利力的教学是一个难点,不容易说清其来由。数学语言以其精准严密而著称,课堂教学中适当使用数学公式推导有时会产生意想不到的好效果。以科里奥利力的产生为例,在课堂教学中使用数学推导,得到跟科里奥利力相联系的加速度,推导过程中清晰说明科里奥利力的来源和物理意义。

Coriolis force can be applied on many explanations, such as Foucault pendulum, trade winds monsoon, tropical cyclone, the influence of earth rotation to molecular spectroscopy, and so on. But, in the university physics class teaching, it is a dififcult point out where the Coriolis force comes from. This makes the Coriolis force a dififculty to be clearly expressed in class. Mathematical language is famous for its accuracy. The appropriate use of mathematical formula and derivation in class teaching can sometimes produce unexpected good results. In this paper, we try to use mathematical formula and derivation in class in classroom teaching of the Coriolis force. During the derivation, we get the formula of the acceleration relative to the Coriolis force. This example also clearly shows the source and the physical meaning of the Coriolis force.
