物理实验教学中的理论分析压力差等于浮力吗？湖北省竹山县宝丰镇中学（４４２２１３）周才宏１初中物理课本中的液体压强和浮力都涉及到了如下的题目：如图１，求物体受到的上、下表面的压强、压力，其压力之差就是物体受到的浮力等。在教学过程中，历届都有部分学生提出...
Theoretical analysis in physics experiment teaching Pressure difference is equal to buoyancy? The Baofeng County Middle School in Zhushan County, Hubei Province (442213) Zhou Caihong 1 The liquid pressure and buoyancy in the junior high school physics textbook all involve the following questions: Figure 1. Find the pressure and pressure on the upper and lower surfaces of an object and the difference in pressure. It is the buoyancy of the object. During the teaching process, some students have submitted questions...
