教材分析《流体压强与流速的关系》这节课选自人教版物理教材九年级第十四章第四节.《流体压强与流速的关系》这节内容放在《大气压强》之后作为它的拓展和必要补充,主要由“流体压强和流速之间存在什么关系?”和“飞机的升力如何产生?”两个核心问题组成.
Teaching material analysis “the relationship between fluid pressure and flow rate” This lesson is from the PEP physics textbook ninth grade Fourteenth Chapter 4. “Fluid pressure and velocity of flow” This section on “atmospheric pressure” as it The expansion and necessary supplementation are mainly composed of two core questions: “What is the relationship between fluid pressure and flow rate?” And “How does the aircraft lift?”
