用物体与气体分子碰撞模型来分析物体的收尾速度以及所受空气阻力。
By the falling body with the gas molecular collision model, the resistance of a falling body is received, and the extreme speed of the falling body is analyzed.
我们日常的固体、液体和气体，它们的热量和热能是从原子和分子在它们到处活泼跳跃和相互碰撞、弹开而上升。
In everyday solids, liquids and gases, heat or thermal energy arises from the motion of atoms and molecules as they zing around and bounce off each other.
假设这里有过多气体，换句话说，如果气体处在一个高压状态下，气体分子间的碰撞将会消耗，电子的能量，同样，什么也没有。
If we have too much gas in here, in other words, if the gas is at too high a pressure, the collisions with the gas molecules will consume the energy of the electrons and, again, we will see nothing.
气体分子间的相互作用力，除碰撞外，也可以忽略不计。
The interactive force between particles, except collisions, is negligible.
