Q:众所周知,人从楼上掉下摔不死也会摔成重伤,可是蚂蚁从高处落下却会安然无恙,其中的秘密是什么呢?A:物体在空气中运动时会受到空气的阻力,其阻力的大小与物体和空气接触的表面积大小有关。越小的物体其表面积大小和重力大小的比值越大,即阻力越容易和重力相平衡,从而不致于下降的速度越来越大,也就是说微小的物体可以在空气中以很小的速度下落,所以蚂蚁落地时速度很小,不致于摔死。
Q: As we all know, people fall from the upstairs will not fall to death will fall into serious injuries, but the ants fall from the top will be safe and sound, which is the secret? A: objects in the air when the exercise will be resistance to the air, its The size of the resistance is related to the size of the surface that the object is in contact with the air. The smaller the size of the object surface area and the greater the ratio of the size of the gravitational force, the more easily the resistance and the balance of gravity, and thus will not decline more and more, which means that tiny objects in the air at a very small speed Whereabouts, so ants landing speed is very small, will not be killed.
