浮力知识历来是初中力学的一个难点,也是中考中容易失分的知识点之一.究其原因,审题不清是一个方面,对浮力的概念和规律理解不到位也是一个重要方面.易错点一:不理解浮力产生的原因,认为只要物体浸在液体中就会受到浮力浸在液体(或气体)中的物体受到的液体(或气体)对它向上的力称为浮力.浮力产生的原因是由于 Buoyancy knowledge has always been a difficulty in junior high school mechanics, but also one of the most easily divisible points in the senior high school entrance examination.The reason is not clear is one aspect of the trial, the concept of buoyancy and understanding of the law is not in place is also an important aspect. One: Without understanding the cause of buoyancy, it is assumed that the upward force of a liquid (or gas) to which an object subjected to buoyancy is immersed in a liquid (or gas) is referred to as buoyancy as long as the object is immersed in the liquid.
