Quickness of motion; swiftness; speed; celerity; rapidity; as, the velocity of wind; the velocity of a planet or comet in its orbit or course; the velocity of a cannon ball; the velocity of light.
Rate of motion; the relation of motion to time, measured by the number of units of space passed over by a moving body or point in a unit of time, usually the number of feet passed over in a second. See the Note under Speed.
I am sensible of the velocity of the moments, and entering that part of my head alert to the motion of the world I am aware that life was never perfect, never absolute. This bestows contentment, even a fearlessness. Harold Brodkey
Windmills, which are used in the great plains of Holland and North Germany to supply the want of falling water, afford another instance of the action of velocity. The sails are driven by air in motion - by wind. Hermann von Helmholtz
The velocity and knee-jerk response to events happening in real time that television brings us precludes any kind of reflection or contemplation and therefore analysis. And that's been one of the greatest political dangers in the post-war era. The idea of the reasoned, thoughtful response goes out of the window. Bill Viola
