物理极值问题是中学物理教学的重要内容之一,在力学、电学等部分均有出现。涉及面广,综合性强,是中学生学习物理的一大难点。高考物理中经常需要通过对物理极值问题的探索和求解总结出物理学的一些基本规律。
The problem of physical extreme value is one of the important contents of physics teaching in middle school, which appears in mechanics and electricity. Involved a wide range of comprehensive strong middle school students to learn a major difficulty in physics. It is often necessary to sum up some basic laws of physics through the exploration and solution of the physical extreme problem in college entrance examination physics.
