每次学到《液体的压强》时,同学们总认为平放在桌面上的物体对桌面的压力就等于该物体的重力,因此容器中的液体对容器底的压力也就等于液体的重力。其实不然,但是同学们又不能理解液体对容器底部的压力与液体的重力到底有没有关系,又可能会有什么关系。所以在解一些有关液体压力压强的题时,经常会不知所措无从下手。正因为这一问题没能很好的解决,使得“压力压强”这一块成为同学们学习初中物理中的一大难关。在教学中,本人也在尝试不同的教法,让同学们更好地理解这一知识点,掌握计算“液体压力压强”的方法。通 Every time you learn the “pressure of liquid,” students always think that the pressure on the tabletop is equal to the gravity of the object, so the pressure on the container bottom is equal to the liquid’s gravity. Actually not, but students can not understand the liquid on the bottom of the container pressure and liquid gravity in the end there is no relationship, but also may have any relationship. So in the solution of some pressure on the topic of liquid pressure, often know what to do without starting. Because of this problem is not well resolved, making “pressure pressure ” This one became a classmate in junior high school physics to learn a big difficulty. In teaching, I also try different methods of teaching, so that students can better understand this knowledge point, master the calculation of “liquid pressure pressure” approach. through
