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 falls | 1 | foot. |
| ½ (half a second) | 4 | feet. |
| 1 second | 16 | ” |
| 2 ditto | 64 | ” |
| 3 ditto | 144 | ” |
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.
