Uma Abordagem Epistemológica dos Invariantes Adiabáticos: como obtê-los

Abstract: RESUMOOs invariantes adiabáticos são importantes ferramentas no estudo dos problemas físicos. Sistemas físicos que envolvem pêndulos e molas são muito empregados em cursos de mecânica clássica como exemplos de aplicação dos formalismos estudados. Assim, este trabalho, utilizando um procedimento didático, tem por objetivo investigar os invariantes adiabáticos para o problema do pêndulo simples, quando o seu comprimento é diminuído lentamente. Com isso, estaremos mostrando de forma clara o procedimento de obtenç… Show more

“…Such magnitudes characterize an important property of this physical system, called adiabatic invariant. The concept of adiabatic invariants in physics is often not even mentioned by teachers in undergraduate courses [1]. Perhaps because the usual derivation of the adiabatic invariance is advanced, making use of Hamilton-Jacobi classical mechanics theory, including canonical transformation in action and angle variables [2].…”
