学习《生物》、《物理》、《化学》一定要动手做实验.在这过程中,还当学习“理想实验”. 什么是“理想实验”呢?现在,就伽利略(1564-1642年)以“理想实验”导致惯性定律的发现为例来说明: 如图1甲所示:将一小球沿一光滑的斜面上从静止滚下来,球接着又滚上第二个光滑的斜面时,所能达到的高度,几乎和它在第一个斜面上开始滚时所处的高度相等,只有微 Learning “biology”, “physics”, and “chemistry” must be hands-on experiments. In the process, we should also study “ideal experiments.” What is “ideal experimentation”? Now, to Galileo (1564-1642) The “ideal experiment” leads to the discovery of the law of inertia as an example to illustrate: As shown in Fig. 1A: When a small ball rolls off a standstill along a smooth slope, the ball then rolls on a second smooth slope. The height that can be reached is almost equal to the height at which it begins to roll on the first slope, only micro
