The velocity of his acts is an indivisible nature in them like the expansive tension in a spring compressed.

The motion of A' is in the direction A'B', but its velocity at the instant is zero.

By a sufficiently accurate practical rule this velocity is eight times the square root of the head or vertical column measured in feet.

The principal shaft makes two hundred revolutions per minute, but the velocity of that of the pumps is but fifty revolutions.

The changes of monsoons are often accompanied with tremendous storms; during one of these, which occurred in September, the velocity of the wind was as much as thirty-seven or thirty-eight meters per second.

I also found that the best flyers were not equal to the feat of keeping me company, when walking at my usual pace; hence I inferred that velocity was a necessary element in flight, and that gravity, so fatal to human attempts to fly, might be made a powerful auxiliary when rightly used.

Experiments on falling bodies, as well as all experience, show that the velocity of every moving body is the product of two factors, which must combine to produce it.

The velocity acquired at the end of the 1st second is not 16-1/12, but 32-1/6 feet per second, and at the end of the 2d second a velocity of 32-1/6 feet has to be added; so that the total velocity at the end of the 2d second becomes 64-2/6 feet; at the end of the 3d, the velocity becomes 96-3/6 feet, at the end of the 4th, 128-4/6 feet, and so on.

The estimated muzzle velocity is 2,216 ft. per second.

Water obeys the laws of gravity, exactly like every other body; and the velocity with which any quantity may be falling is an expression of the full amount of work it contains.

The effective velocity will be the difference between these quantities, or 4.997 feet per second.
