| Jan 27, 2020 at 3:35 | comment | added | releseabe | BTW, Euler is pretty well known as one of the most prolific mathematicians in history -- the constant e is not what I think about when I think of him. | |

| Jan 26, 2020 at 13:34 | comment | added | releseabe | I would bet that Aristotle or those before him would not have understood fps and, say, "impact" of an arrow although they would have talked about how far a man could march in a day. I think we can leave the answer alone. | |
| Jan 26, 2020 at 13:07 | comment | added | Conifold | @releseabe The general idea of speed as distance/time was loosely used long before Aristotle, and metrics like fps for uniform motion appear in ancient astronomy, for example. That the speed of arrows, etc., decays was discussed by medieval impetus theorists, see Why don't we learn Buridan's laws of motion? Tartaglia was aware of air resistance before Newton, or even Galileo. But my problem with adding it is that what was done before 17th century can hardly be characterized as experimental measurements, and even Newton did not do it for projectiles. | |
| Jan 26, 2020 at 12:52 | comment | added | releseabe | whether aristotle would have even conceived of fps as a metric or understood that this was at a maximum at the bow -- not sure that anyone before newton would have. | |
| Jan 26, 2020 at 12:50 | comment | added | Conifold | @releseabe Sorry, but I am unsure for what exactly? | |
| Jan 26, 2020 at 12:45 | comment | added | releseabe | i think that this would be a good place for that. | |
| Jan 26, 2020 at 12:41 | comment | added | Conifold | @releseabe Ok, but do you want me to add something to the answer? | |
| Jan 26, 2020 at 12:41 | comment | added | releseabe | i am saying the speed of arrows would not have been of interest to anyone in ancient times, i don't think. range would have been but the relationship between speed and range would not have been understood. | |
| Jan 26, 2020 at 12:34 | comment | added | Conifold | @releseabe Are you asking how the speed/range of arrows was measured? | |
| Jan 26, 2020 at 12:32 | comment | added | releseabe | yes but related. your answer makes it clear that it was not until fairly modern times that speed was measured and of course the thing that the military was interested in would have been range which after Newton would have been understood to be related to speed. | |
| Jan 26, 2020 at 12:30 | comment | added | Conifold | @releseabe That sounds like a separate question, but Aristotle and other ancients only dealt with speed for uniform motion where these issues did not arise. | |
| Jan 26, 2020 at 12:28 | comment | added | releseabe | I would wonder if Aristotle would have understood a metric like feet per second -- the relationship between distance traveled per unit time (when say an arrow left the bow) and impact or range would not have been obvious. In fact, I wonder when FPS would have first been understood in this way. | |
