一、常见的两类动力学图象问题1.已知物体在某一过程中所受的合力(或某个力)随时间的变化图象,要求分析物体的运动情况。2.已知物体在某一过程中速度、加速度随时间的变化图象,要求分析物体的受力情况。二、解决图象综合问题的关键1.分清图象的类别:即分清横、纵坐标所代表的物理量,明确其物理意义;掌握物理图象所反映的物理过程,会分析临界点。2.注意图象中的一些特殊点所表示的物理意义:图象与横、纵
First, the common two types of dynamic image problem 1. Known objects in a process suffered by force (or a force) changes over time images, requiring analysis of the movement of objects. 2. Known objects in a certain process speed, acceleration changes over time images, requiring analysis of the object force situation. Second, the key to solve the problem of image synthesis 1. To distinguish between the categories of images: the distinction between horizontal and vertical physical representation of the physical, clear physical meaning; master physical image reflects the physical process will analyze the critical point. 2. Note that some of the special points in the image that the physical meaning: image and horizontal, vertical
