有一天,天气预报本来是小雨,结果小雨很快转变成暴雨,由此引起同学们争论大雨滴、小雨滴谁落得快,还是同样快的问题。请你也来参加讨论,并说明道理。参考答案:大雨滴落得快。因为雨滴下落时受两个力作用:一是雨滴的重力,方向向下;二是空气阻力,方向向上。空气的阻力与雨滴的横截面积成正比,且随雨滴下落速度的增加而增加。当阻力与重力相等时,雨滴将匀速下降,这个速度叫极限速度。 One day, the weather forecast was originally a light rain. As a result, the light rain turned into a heavy rain quickly. As a result, students were debating the heavy raindrops. Please also come to discuss and explain the truth. Reference answer: heavy rain drops quickly. Because the raindrops fall by two forces: First, the gravity of raindrops, the direction down; Second, the air resistance, the direction up. The resistance of the air is proportional to the cross-sectional area of ​​the raindrops and increases with the falling raindrop velocity. When the resistance and gravity are equal, the raindrop will drop uniformly, this speed is called the limit speed.
