浮力问题是力学乃至初中物理学的重点和最困难的问题之一.浮力问题能力高,综合性强.重点考查学生的观察能力、实验能力、思维能力和灵活运用浮力知识解决实际问题的能力.应用阿基米德定律来解决有关浮力的计算题,是初中物理学习的一个难点,在解浮力习题时主要应用两个方面的知识,一个是阿基米德定律,另一个是力的平衡知识.浮力习题变化虽多,但是只要仔细分析一下,就可以发现它们可划分为两种基本类型:一种是物体浮
Buoyancy problem is one of the most important and most difficult problems in mechanics and even junior middle school physics.On the one hand, the problem of buoyancy is highly capable and comprehensive, focusing on students’ abilities of observation, experiment, thinking and flexible use of buoyancy knowledge to solve practical problems. The application of Archimedes ’law to solve the calculation problem of buoyancy is a difficult point in junior middle school physics learning. Two main aspects are applied in solving buoyancy problems, one is Archimedes’ law and the other is balance of power Buoyancy exercises vary, but as long as careful analysis, you can find that they can be divided into two basic types: one is the object floating
