物体浮沉条件的应用涉及的考点是阿基米德原理,着重考查考生对浮沉条件、原理的理解、应用和识图能力。解决这类问题的一般思路和方法是:首先,根据题目给出的图形,分析物体在液体中的状态;其次,利用物体的浮沉条件,分析物体所受重力和浮力的大小关系或者物体密度和液体密度的关系,分析过程中确定力的关系要从力的角度去判断,确定密度的关 The application of object floating conditions involving test sites is Archimedes principle, focusing on examining candidates on the sunken conditions, principles of understanding, application and vision ability. The general idea and method to solve this kind of problem are as follows: Firstly, we analyze the object’s state in the liquid according to the figure given by the topic; secondly, by using the surface condition of the object, the relationship between gravity and buoyancy, Liquid density, the relationship between the determination of force in the analysis process to judge from the perspective of force to determine the density of the off
