实验1.演示动量守恒本实验需要一只直径约为10英时的绣花圈(从工艺商店买得),两只直径约为1英吋的金属球(一只铝制,一只钢制),一把普通的餐刀,一张半英时厚的有机玻璃板。实验时,将有机玻璃板放在幻灯机的上方,将绣花圈放在玻璃板上,但不必固定。将两只金属球相互接触靠放在绣花圈的内缘时,用餐刀的手柄往两只球之间坚直向下一击,使两球分离。动量守恒要求两球沿绣花圈通 Experiment 1. Demonstrate Conservation of Momentum This experiment requires an embroidered wreath of about 10 inches in diameter (available from the craft shop) and two metal spheres (one aluminum and one steel) about 1 inch in diameter. , An ordinary table knife, a half glass plate thick plexiglass. In the experiment, the plexiglass plate was placed on top of the slide and the embroidered wreath was placed on the glass but it did not have to be fixed. When the two metal balls are placed in contact with each other on the inner edge of the embroidered wreath, the handle of the dining knife strikes the two balls and strikes them down, causing the two balls to separate. Conservation of momentum requires two balls along the embroidery wreath
