在研究运动物体的加速度、外力和物体本身的质量三个物理最之间的关系时.课本中“图3—4研究牛顿第二定律的探索规律的实验”虽简单易懂但实验常常不是很理想,故此对高中课本中该实验作了一些改进。现将改进的实验供大家探讨,避一步研究提高演示效果.实验器材是用电阻率演示器改装,把骑滑块改为单
In the study of the relationship between the acceleration, external force of a moving object, and the mass of the object itself, the textbook’s “Figure 3-4 examines the law of Newton’s second law of law”, although it is easy to understand but the experiment often Not ideal, so some improvements have been made to the experiment in high school textbooks. Now we will improve the experiment for everyone to explore, avoid step by step to improve the demonstration effect. Experimental equipment is modified with a resistivity demonstrator, the rider slider to single
