A mecânica de Galileu

A Queda Livre – Galileu Descreve o Movimento
Abordaremos o desenvolvimento de um importante exemplo de investigação básica: o estudo dos corpos em queda livre feito por Galileu Galilei. Embora o problema físico da queda livre seja por si só interessante, o estudo será orientado para a maneira como Galileu, um dos primeiros cientistas modernos, apresentou os seus argumentos. A sua perspetiva do mundo, a sua maneira de pensar, o seu uso da matemática e a sua confiança nos testes experimentais, marcam o estilo da ciência moderna. É por isto que estes aspetos do seu trabalho são tão importantes para nós como os resultados reais da sua investigação. Ler mais
