图象法是物理学中解决问题的一种重要手段,它的优势是将抽象物理问题直观化、形象化,从而简化处理过程,达到准确快速解决问题的效果.在研究运动学的问题中,v-t图能将复杂的运动问题清晰化,指引我们从复杂的公式中选择最佳的方法,完成用解析法较难完成的任务.笔者整理了一些用v-t图巧解运动学难题与只能用v-t图解决的运动学问题,旨在抛砖引玉,体现v-t图的
Image law is an important means to solve the problem in physics, and its advantage is to abstract and visualize the abstract physical problems so as to simplify the process and achieve the accurate and rapid solution to the problem.In the study of kinematics, vt map can clear the complex movement problems, guide us to choose the best method from the complex formula to complete the task more difficult to complete with the analytic method. I sorted out some vt diagrams to solve kinematic problems and can only be used Vt map to solve the kinematic problems, designed to initiate, reflecting the vt map
