人造卫星的运动属于宏观现象,氢原子中电子的运动属于微观现象,但由于支配卫星和电子运动的力都遵循平方反比律,故它们在物理模型上和物理运动规律的描述上非常相似(即描述运动的物理量与规道半径的关系十分相似),如果我们在学习的过程中,能够紧紧抓住相似点,则可以提高我们分析问题和解决问题的能力.一、向心力由谁提供如何表示向心力 The movement of satellites is a macro phenomenon. The movement of electrons in hydrogen atoms belongs to the microscopic phenomenon. However, since the forces governing the movement of satellites and electrons follow the inverse square law, they are very similar in physical model to the description of the laws of physical movement Describing the relationship between physical quantities and the radius of the gauge is very similar), if we can grasp the similarities in the process of learning, we can improve our ability to analyze and solve problems.
