that therefore 1 ⁄ m in the one, is equal to 1 ⁄ m in the other: But in the Line of Projection (suppose) 1 ⁄ m f (such a Part of the Force impressed, and a Celerity answerable:) in the Line of Descent, 1 ⁄ m g such a Part of the Impulse of Gravity.
- Those for the Line of Descent (of the some Body) are all equal, each to other: Because
g (the new Impulse of Gravity) in each Moment is supposed to be the same.
- But what is the Proportion of f to g (that of the Force impressed, to the Impulse of Gravity in each Body) remains to be inquired by Experiment.
- This Proportion being found as to one known Force; the same is thence known as to any other Force (whose Proportion to this is given) in the same uniform Medium.
- And this being known, as to one Medium; the same is thence known as to any other Medium, the Proportion of whose
