RATE OF THE FALL OF BODIES.

A body falls in gravity precisely 16-1/16 feet in a second, and the velocity increases according to the squares of the time, viz.:

In ¼ (quarter of a second) a body falls1foot.
½ (half a second)4feet.
1 second16
2 ditto64
3 ditto144

The power of gravity at two miles distance from the earth is four times less than at one mile; at three miles nine times less, and so on. It goes on lessening, but is never destroyed.—Notes in various Sciences.
