Center , the difference being so small as by no means to be discovered in Practice . The Opposition of the Air , 'tis true, is considerable against all light Bodies moving through it, as likewise against small ones (of which more hereafter) but in great and ponderous Shot, this Impediment is found by Experience but very small, and may safely be neglected.
Propositions concerning the Descent of Heavy Bodies, and the Motion of Projects.
Prop. I. The Velocities of Falling Bodies, are proportionate to the Times from the beginning of their Falls.
This follows, for that the Action of Gravity being continual , in every Space of Time, the falling Body receives a new Impulse, equal to what it had before, in the same Space of Time, received from the same Power: For Instance, in the first Second of Time, the falling Body has acquired a Velocity , which in that time would carry it to a certain Distance, suppose 32 Foot, and were there no new
