很多学生在初学浮力的有关内容时,由于概念把握不清,往往会对一些情况产生误解, 针对在教学中出现的一些情况,现对容易出现的误区阐述如下,以供参考: 一、认为上浮的物体受到的浮力大,下沉的物体受到的浮力小乒乓球和一块大石头同时浸没在水中,放手后大石头下沉,乒乓球上浮,误认为乒乓球 Many students have misunderstood the concept of buoyancy when they begin to learn about buoyancy, and they often misunderstand certain situations. In view of the situations that occur in teaching, the following are the embarrassing misunderstandings. For reference: The buoyancy of the object is large, the buoyancy of the sinking object is small. Table tennis and a large stone are immersed in the water at the same time. After the release, the big stone sinks and the table tennis floats. It is mistaken for table tennis.
