压强与浮力是力学知识的重点,也是同学们学习的难点.在中考中题型多样,是力学中计算要求较高的内容,试题一般为中等难度,也常常综合浮力、压强、二力平衡、密度、简单机械等知识进行难度较大的考查.下面列举出一些与该章有关的易错知识点加以诊断,希望对同学们的学习有一定的帮助. Pressure and buoyancy are the focus of mechanical knowledge, but also difficult for students to learn in the middle school entrance examination in a variety of questions, is calculated in the mechanics of the higher content of the questions are generally moderate difficulty, and often integrated buoyancy, pressure, balance of forces, Density, simple machinery and other knowledge of the more difficult test below lists some of the chapter error-prone knowledge points to be diagnosed in the hope that students have some help learning.
