机械能守恒定律是中学物理中的一个重要定律,是高考的热点、重点问题.要彻底掌握机械能守恒定律的应用,首先最重要的是判断物体或系统在整个过程中机械能是否守恒,然后才能应用机械能守恒定律解决问题,所以对机械能是否守恒条件的判断尤为重要.下面对机械能守恒条件归类如下:一
The law of conservation of mechanical energy is an important law in the physics of middle schools. It is a hot topic and a key issue in the college entrance examination. To thoroughly grasp the application of the law of conservation of mechanical energy, the first and most important thing is to determine whether the mechanical energy of an object or a system is conserved during the entire process and then the mechanical energy can be used. The law of conservation solves the problem, so the judgment of whether the mechanical energy is conserved is particularly important. The following conditions for the conservation of mechanical energy are categorized as follows:
