动力学是历年高考考查的重点知识点之一,近些年来,面对动力学部分灵活的题型,巧妙的设问,众多师生充满疑惑,感觉无处下手。以下是我在教学工作中总结的一点复习动力学知识的教学经验,跟各位交流,希望能对广大同行和同学们有所帮助。一、三类基本问题从力对物体的作用时间和空间关系看,动力学问题可分为力对物体的瞬间作用,力对物体的时间积累作用和力对物体的空间积累作用三类基本问题,它们分别遵从牛顿第二运动定律,动量定 Kinetics is one of the key knowledge points in examining college entrance examination over the years. In recent years, in the face of some flexible motivation problems, clever questioning and asking, many teachers and students are full of doubts and feel nowhere to start. The following is a summary of my teaching work a little review of kinetic knowledge of teaching experience, to communicate with you, hoping to help the majority of peers and students. First, the three types of basic issues From the force on the role of objects in time and space relations, kinetic problems can be divided into force on the object’s momentary effect, force on the object’s role in the accumulation of time and space objects on the role of space accumulation of three basic issues , Respectively, they follow the Newton’s second law of motion, momentum set
