解决传送带问题需要用到运动学规律、牛顿运动定律、动能定理和功能关系等高中物理主干知识,解答过程中涉及图象法、程序法和守恒思想等,所以,试题内容丰富,综合性强,与大分值能较好地匹配.从试题的背景看,可以联系生活实际,因此传送带能集当下多个流行要素为一体,成为较好的命题素材.为此,我们在学习、复习中要特设专题,以厘清传送带的解答技巧,提高思维活动能力.一、以水平传送带为模型探究功能关系 Solve the problem of conveyor belt need to use the laws of kinematics, Newton’s law of motion, kinetic energy theorem and functional relationship of high school physics backbone knowledge, answer the process involves image law, procedural law and conservation ideas, so the questions, rich in content, comprehensive, And the score can be a good match.From the background of the test questions, you can contact the actual life, so the conveyor belt can set the current multiple elements as one, become a better proposition material.To this end, we study, review Ad hoc topics to clarify the answer to the skills of the conveyor belt to improve the ability of thinking activities.A horizontal conveyor belt as a model to explore the functional relationship
