摘要
"碰撞模型"是物理问题中一项重要内容,它源于生活,又能指导生活。利用碰撞过程中所遵守的物理规律很好解决了现实生活中所发生的相关的物理问题。以篮球运动员"骑扣"现象以及影视作品中的特效为例,结合相应物理规律给予说明和解答,供物理教育工作者能获得启迪和思考。
Collision model is an important part of physical problems. It comes from life,and is also able to guide life. It can well resolve the physical difficulties in realty to use the physical laws observed in the collision process. This paper takes＂ride buckle＂phenomenon in basketball games and some effect movies as examples,and gives some instructions combined with corresponding physical laws. I hope it will help physical educators obtaining some enlightenment and thought.
