第六章 “浮力” 浮力和物体的浮沉条件在生产技术中有许多重要的应用,本章在前几章所学知识的基础上学习有关浮力的知识。这部分知识的重点是阿基米德定律和物体的浮沉条件。要求学生知道浮力产生的原因,掌握阿基米德定律,会计算有关浮力的简单问题,知道物体的浮沉条件,了解浮沉条件的应用。研究浮力和物体的浮沉,需要综合运用前 Chapter 6 “Buoyancy” Buoyancy and floatation conditions of objects have many important applications in the production technology. This chapter learns about buoyancy based on the knowledge gained in previous chapters. The focus of this part of the knowledge is the Archimedes’ law and the floating conditions of the object. Students are required to know the cause of buoyancy and to master Archimedes’s law. They will calculate simple questions about buoyancy, know the floatation conditions of objects, and understand the application of floating conditions. To study the buoyancy and floatation of objects, before comprehensive application
