After the collision, m2 and m1, let it have a velocity v1 prime.
它们有速度，当它们相互碰撞时，实际上它们有时反弹。
They have Velcro, so when they hit each other, Sometimes they bounce, actually.
微型车和中型车均以每小时40英里的速度行驶，因此碰撞时速度为每小时80英里。
Both the minicars and midsize cars were traveling 40 miles per hour, so the crash occurs at 80 M.P.H.
通过测量因纳斯卡板块挤压海岸发生碰撞造成的地面的缓慢上升与下降，他们能够估算压力的实际聚集速度。
By measuring the slow rising and falling of the ground as the inexorable collision of the Nazca plate squeezed the coast, they could calculate how fast strain was actually building.
他们必须放慢速度到每小时19英里左右，万一发生碰撞事故，人员死亡率低于5%。
They must slow down to about 19mph, a speed that, in case of collision, kills less than 5%.
我先使这两个碰撞，它们两个相碰，当它们碰撞的时候，我期待速度是一半。
And first I'm going to slam these two onto each other, and so when they collide, I expect the speed to be half.
由于磁化空腔的效能慢慢降低，那么那些速度还很快的原子就很容易逸出，而其余的气体粒子在不断的碰撞中消耗能量，使得温度降低。
As the height of the magnetic barrier is slowly lowered, the fastest atoms leave the bottle and the remaining gas rethermalizes via elastic atomic collisions at lower and lower temperatures.
我们只看台球-，完全忽略乒乓球-，来看看台球的速度，它实际未受碰撞影响。
Look at the billiard ball alone — - forget the ping-pong ball — and try to see that the speed of the billiard ball is practically unaffected by the collision.
甚至于时间准确性也在加强，（在Hatfield铁路碰撞之后，时间准确有所降低，同时大部分的铁路都进行速度限制）,88%的火车多少的准时的。
Even punctuality—which fell after the Hatfield rail crash in 2000, when speed restrictions were introduced across much of the network—is improving, and 88% of trains arrive more or less on time.
它们被聚集起来投入实验，此时速度大约是5米每秒——仅为空气中分子自由碰撞速度的百分之一。
They are gathered up and injected into the quantum experiment at speeds of around five meters per second - just a hundredth the speed of the molecules flying around in the air.
(眨眼淡入淡出速度)：碰撞时淡入淡出速度。
采用该模型模拟了脑部正碰的过程，得到了碰撞过程的速度、能量、应变和应力曲线。
