一、现在比较流行的斜面实验器材如图所示的实验器材能比较好的演示一侧的斜面从较大的倾斜度逐渐过渡到水平,这样可以改变前些年我们讲到伽利略理想斜面实验时依赖多媒体课件的现象,让学生有一种眼见为实的感觉,但此实验有一个缺点,就是摩擦力还较大,小球无法来到等高的位置,如果铲除了学生这一疑虑,就可以很好地突破本节课思维难点,鉴于此设计了气垫管实验。
First, the more popular slope experiment equipment As shown in the experimental equipment can be better demonstration side of the ramp gradually transition from a larger slope to the level, so you can change a few years ago when we talk about Galileo ideal bevel experiment Depends on the phenomenon of multimedia courseware, so that students have a see-through feeling, but this experiment has a drawback, is the friction is still large, the ball can not come to the contour position, if the eradication of the student’s doubt, you can Well break through this lesson difficult thinking, in view of this design of the air tube experiments.
