Resumo: | In this paper we discuss a new experimental demonstration of the independence of the properties of bodies (mass, chemical composition, shape, etc) in free fall. This is one of the simplest experiments in Mechanics, though it’s one of the most important ones, having been repeatedly carried out and rethought by several scientists such as Galileo and Newton. Our version of this famous experiment uses one bottle (closed and transparent), in which we introduce a feather and a stone, observing the simultaneous free fall of these bodies. Because it’s not necessary to create vacuum, this version can be repeated by teachers and students either in High Schools or Universities in any environment. Thus its viability and applicability in the classroom is evident. |

É uma das experiências mais simples, porém uma das mais importantes da Mecânica, tendo sido realizada e repensada repetidamente por diversos cientistas tais como Galileu e Newton. Nossa versão é introduzir dentro de uma garrafa fechada e transparente uma pena e uma pedra observando a queda simultânea destes corpos. Por não haver a necessidade de produzir vácuo, esta versão pode ser repetida por qualquer aluno e professor de ensino médio e universitário em qualquer ambiente, evidenciando sua viabilidade e aplicabilidade na sala de aula.Imprensa Universitária - UFSC2007-09-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/fisica/article/view/6237Caderno Brasileiro de Ensino de Física; v. 24 n. 3 (2007); 319-3252175-79411677-2334reponame:Caderno Brasileiro de Ensino de Física (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/fisica/article/view/6237/5788Lunazzi, Jose JoaquínPaula, Leandro Aparecido Nogueira deinfo:eu-repo/semantics/openAccess2022-11-29T18:52:49Zoai:periodicos.ufsc.br:article/6237Revistahttp://www.periodicos.ufsc.br/index.php/fisicaPUBhttps://periodicos.ufsc.br/index.php/fisica/oaicbefisica@gmail.com||fscccef@fsc.ufsc.br|| cbefisica@gmail.com2175-79411677-2334opendoar:2022-11-29T18:52:49Caderno Brasileiro de Ensino de Física (Online) - Universidade Federal de Santa Catarina (UFSC)false |
