Description03. Реакциска сила кај архимедовиот закон.ogv |
Македонски: Опит кој ја демонстрира реакциската сила кај Архимедовиот закон, односно реакциската сила на Архимедовата сила. Кога шипката се потопува во водата, се појавува силата на потисок (Архимедовата сила), со која водата која дејствува на шипката вертикално нагоре. Согласно третиот Њутнов закон (на секоја сила одговара друга сила која има еднаков интензитет со првата и дејствува во спротивна насока), се појавува сила со еднаков интензитет како и силата на потисок но која дејствува на водата во спротивна насока (надолу). Тоа дејство од водата се пренесува на садот и на тасот и поради тоа доаѓа до пореметување на рамнотежата. Треба да се забележи дека прачката не се става да тежи во чашата, туку тежината се зголемува само со вметнување на тело во водата. Изведено и објаснето од проф. Оливер Зајков. Институт за физика на Природно-математичкиот факултет во Скопје.
English: Experiment demonstrating the reaction force of the upward buoyant force. When the metal bar is immersed in water upward buoyant force appears, which acts on the bar. According to the Newton's Third Law, downoard force appears, which acts on the water. The action is transferred to the bottom of the container and hence to the scale. Thereby, the balance of the scale is disturbed. Note that the bar isn't acting on the bottom of the container directly. Performed and explained by Prof. Oliver Zajkov at the Physics Institute at the Ss. Cyril and Methodius University of Skopje, Macedonia.
Français : L'expérience démontre la poussée d'Archimède en plongeant une tige de métal dans un contenant d'eau. Ainsi, lorsque la tige est immergée, l'eau exerce une force sur la surface de celle-ci. Selon la troisième loi de Newton, la force exercée vers le haut doit être compensée par une force de même grandeur en sens opposé, vers le bas. Celle-ci est transmise au contenant, ce qui abaisse la balance et ce, sans que la tige ne touche le fond du contenant Expérience réalisée et expliquée par le professeur Oliver Zajkov de l'Institut de physique de l'université Saints-Cyrille-et-Méthode de Skopje de Macédoine. |
