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.
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.
