Análise do movimento de projéteis na presença de forças dissipativas para o regime de altas velocidades

Abstract: Neste trabalho desenvolvemos as equações referentes ao movimento de uma esfera lisa na presença de forças de arrasto, no regime de altas velocidades, onde a força resistiva é proporcional ao quadrado de sua velocidade. Esse regime é comumente encontrado em várias situações do cotidiano em que objetos de toda natureza são arremessadas no ar. As equações que são estudadas nos cursos básicos de graduação desconsideram o arrasto do ar e, portanto, são equações idealizadas, não condizentes com a real natureza do mo… Show more

“…[2]. Finally, we would like to highlight that even if one accommodates oneself to the incorrect equations of motion presented in [3], the methods employed by the authors demonstrate a level of proficiency that surpasses the typical expectations for a student enrolled in an undergraduate introductory course. However, it should be acknowledged that while the simplified scenario incorporating linear drag force may not accurately represent reality in high-speed situations, it still provides a valuable demonstration of how drag forces impact the trajectory and behavior of moving objects in a simpler analytical and exact manner.…”
