动量与机械能守恒是历年高考理科综合物理命题的重点、热点和焦点,也是广大考生的难点,它主要考查两个定理和两个守恒的运用,动量定理、动能定理、动量守恒定律和能量守恒定律是整个高中物理学习的重点,两个定理和两个守恒贯穿于整个高中物理学习的始终,是联系各部分知识的主线,它不
The conservation of momentum and mechanical energy is the focus, hot spot, and focal point of the comprehensive physics propositions of college entrance examinations over the years. It is also a difficult point for the majority of candidates. It mainly examines two theorems and the application of two conservations, the momentum theorem, kinetic energy theorem, the law of conservation of momentum, and the law of conservation of energy. It is the focus of physics learning in the whole high school. The two theorems and the two conservations are always throughout the physics study of high school. It is the main line connecting all parts of the knowledge. It does not
