为了更直观地理解物理课中作用 力与反作用力的定律,以及该 定律在火箭上的应用,我们可以用 两个玻璃的眼药水瓶和铁丝、木板 等简单的材料制作一个火箭模型。 这个火箭模型由底座、支杆、旋臂和 火箭体几个部分组成,如图1所示。 底座用木板制成:大圆直径 150 毫米、厚10毫米,小圆直径100毫 米、厚5毫米,在中心钻一直径12 In order to understand more intuitively the laws of forces and reaction forces in physics classes and the application of this law to rockets, we can use a glass of eye drops and a simple material such as iron wire and wood to make a rocket model. This rocket model consists of several parts of the base, struts, spiral arms and rocket bodies, as shown in Figure 1. The base is made of wood: Large circle diameter 150 mm, thickness 10 mm, small circle diameter 100 mm, thickness 5 mm, drill a diameter of 12 in the center
