高二物理“伯努利方程”一节中,教材设计了用漏斗吹乒乓球和吹纸的演示实验,实验简单易做,效果明显.实验现象表明:在流动的流体中,压强跟流速有关,图1流速大的地方压强小,流速小的地方压强大.在教学中我们用矿泉水瓶制作了几个简易装置,演示流体压强跟流速关系的现象,也取得了?
High school physics “Bernoulli equation” section, the textbook designed with funnel blowing table tennis and blowing paper demonstration experiment, the experiment is simple and easy to do, the effect is obvious.Experimental results show that: in the flowing fluid, the pressure with the flow rate, Figure 1 where the pressure is small, small pressure, small flow velocity pressure in the teaching where we used a few simple devices made of mineral water bottles, showing the relationship between fluid pressure and flow phenomena, but also made?
