在中学物理教学中,让学生在理解相对运动、矢量合成等知识的基础上将能使得某些初看起来相当困难的运动学问题的处理大为简化,而其物理图象则更加直观明晰。以下举例说明。从“猎猴”问题谈起这是一个众所周知的趣味性问题(图1):树上M处有一只猴子,一猎人在O处用枪向其瞄准,当击发的瞬间猴子因受惊而下落(可看作自由落体),问子弹还能击中 In the middle school physics teaching, students can simplify the processing of some kinematic problems that are difficult at first sight on the basis of understanding relative motion, vector synthesis and other knowledge, and their physical images are more intuitive and clearer. The following is an example. From the “hundred monkey” issue, this is a well-known and interesting issue (Figure 1): There is a monkey at M in the tree, and a hunter aims at it with a gun at O, and when it is fired, the monkey falls because of fright. Can be seen as free fall), asking the bullet to hit
