教学要求与目的:使学生熟练运用运动学知识求解追赶、相遇问题,掌握处理此类问题的方法;教学重点和难点:重点:追赶、相遇问题的处理方法.难点:如何根据条件选择解题途径.课型:习题课、解题方法介绍教学时间:1课时.教学内容及过程:教师引言:追赶、相遇问题是运动学中常见问题,由于此类问题涉及到两个物体的运动,且运动状态一般不同,因此很多同学处理此类问题都有一定难度.其实在弄清两物体运动状态及规律的基础上,恰当选择解题途径,问题也就不难解决.今天这一节课就介绍处理追赶、相遇问题的方法.
Teaching requirements and purposes: to enable students to skillfully use kinematics knowledge to solve problems of catch-up and encounter, to master methods for handling such problems, and to focus on teaching and difficulty: Focus: How to catch up and meet problems. Difficulties: How to choose the solution according to the conditions Course type: Exercise class, problem solving method Introduction Teaching time: 1 class hour. Teaching content and process: Teacher introduction: The problem of catch-up and encounter is a common problem in kinematics. As such problems involve the movement of two objects, and sports The state is generally different, so many students have a certain degree of difficulty in dealing with such problems. In fact, on the basis of clarifying the state of motion and laws of two objects, the appropriate choice of problem solving approaches will not be difficult to solve the problem. This lesson is introduced today. Deal with the way to catch up, meet problems.
