动量守恒与能量守恒是近几年高考理科综合物理命题的重点、热点和焦点,也是广大考生普遍感到棘手的难点之一。动量守恒与能量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。它不仅为解决力学问题开辟了两条新的重要途径——动量和能量的观点,同时也为我们分析问题和解决问题提供了重要依据。守恒思想是物理学中极为重要的思想方法,是物理学研究的极高境界,是开启物理学大门的金钥匙,同样也是对考生进行方法教育和能力培养的重要方面。因此,两个守恒可谓高考物理的精华所在,重中之重,当然也就是高考的重点、焦点和热点,并且时常作为压轴题出现在物理试卷中。
The conservation of momentum and the conservation of energy are the focus, hotspot, and focus of the comprehensive physics proposition in the college entrance examination in recent years, and it is also one of the most difficult problems for the majority of candidates. Conservation of momentum and conservation of energy throughout the entire high school physics study are the main lines linking various parts of knowledge. It not only opens up two new important ways to solve mechanics problems: the view of momentum and energy, but also provides an important basis for us to analyze problems and solve problems. Conservative thinking is an extremely important method of thought in physics. It is an extremely high realm of physics research. It is the golden key that opens the door to physics, and it is also an important aspect of method education and ability cultivation of candidates. Therefore, the two conservations can be regarded as the essence of college entrance examination physics, and the most important thing is, of course, the focus, focus and hot spot of the college entrance examination, and often appear as the finale in the physical examination paper.
