So if I strobe this apple while it was falling I would see the separation, when it strobes to increase with time, because the velocity goes up with time.

如果用频闪相机拍摄，苹果下落的过程，可以看到频闪的间隔，苹果的距离，随着时间不断变大，因为速度随着时间而变大。

The falling object, after traveling a certain distance through the air reaches a final speed, or "terminal velocity," because the object's friction with the air slows the fall.

物体在下落一定距离后由于空气阻力都会达到一个终极速度。

Velocity has been falling-which means each dollar the Fed prints has less oomph. POINT: For QE.

对QE的观点：如今周转率正在下降——这意味着联储印出的每一个美元都不太有魅力。

It knows that this particle happened to have a height of 15, at the time of 0, and a velocity of 10, and it is falling under gravity with an acceleration of -10.

这个质点恰好处在高度为15的地方,零时刻,初速为10,并在重力作用下以-10的加速度下坠

M2 Velocity is falling as well.

FORBES: Goodbye Recovery, Hello Recession

Falling velocity is a sign that consumers and businesses are losing confidence in the future.

FORBES: Goodbye Recovery, Hello Recession

The study of the past doesn't yield unalterable laws that allow one to predict the future with the same certainty that a physicist can chart the trajectory and velocity of a falling object.
