Said momentum is a sixth century Alexandrian scholar John 斐劳波诺斯 (john philoponos) raised. He denied the celestial gods driven by the view of nature. He believes that the beginning of creation God gives celestial kind of "momentum." This is not a power over time, this momentum can be maintained forever movement of objects down. Thus, the movement of objects generally do not need to have a facilitator and it is often in contact.
In the Middle Ages, said momentum by Muslims before returning to Europe. The fourteenth century, the University of Oxford nominalist William of Ockham was the beginning of the dominant critique of Aristotle's mechanics. He agreed vision 斐罗波诺斯, saying that God could give the beginning of a celestial body with the passage of time without momentum, assuming that there is no need to promote a variety of celestial gods angel. He completely deny the existence of God first prove that celestial motion requires a mover who raised Thomas Aquinas. He can make a piece of iron without the need to move in accordance with the magnet direct contact with the facts, objects do not necessarily need a movement sustained contact with another object role.
Participants in the discussion as well as the University of Oxford momentum mainly Walter Burley (walter burley), Richard Hsu Sasi (richard suiceth) and Walt Haiti Spree (walter heytesbury), but this doctrine was soon lose power , to the fifteenth century, the Oxford scholar Aristotle taught most of the physics.
But the momentum has been further developed, said the University of Paris, a staunch supporter of President of the University of Paris hate け soil mace Paul ╦ ean buridan) and Albert are the momentum theory. Paris says momentum is the largest school representative Nicolas Orie Sim (nicolas oresme), he created a graphically performance speeds. He used a horizon on behalf of moving objects go the distance, and then draw a vertical and horizon on the horizon at the end of the line, which represents the speed of an object known point. The upper end of the vertical line to link up to form a geometric, rectangular uniform to show that sport is a triangle to show that the movement is not uniform, is to show that the curve is irregular movement or "uneven unevenly."
In fact, said momentum to the fifteenth century has been a bit bad, but said the momentum in the early sixteenth century was also taught. The doctrine of the recession is dry from the British Horse Farm celecoxib in (marsile of ingham) began. He envisioned the same momentum as heat. The farthest part of the movement away from the source of the object, the weakest momentum, like a stick one end furthest away from heat sources, like the coldest, the object away from its promoters, the momentum on the average distribution to all parts of the body, like the stick away from fire After that, heat it evenly out, the final momentum gradually decline, as dissipated as heat stick. |
