Note 49 — AN UNIVERSAL DICTIONARY OF THE MARINE. (continued 8)

Weight, or gravity, always operates equally on a falling body; for as it always subsists in an equal degree, it must perpetually act with equal force, or produce always the same effect in the same time. So if, in the first instant of falling, it communicates to a body a certain force sufficient to move a certain space, it must, in every following instant, communicate a force capable of moving it the like space, and by this means the velocity of a falling body is every moment accelerated; for if it has one degree the first instant, it will have two the second, three the third, and so on. Hence it must move different spaces every instant, and by that means describe the curve-line above mentioned.
