UTILIZANDO O TRACKER PARA A OBTENÇÃO DA CARGA ESPECÍFICA DO ELETRON.

Abstract

O Tracker é uma aplicação gráfica em Java publicada mediante a licença GPL que permite analisar vídeos do ponto de vista físico muito utilizado para estudo de fenômenos correlacionados à mecânica e cinemática. Neste trabalho, apresentamos uma proposta de aplicação do Tracker para o desenvolvimento de experimentos em Física Moderna, particularmente na determinação da carga específica do elétron. A metodologia desenvolvida permitiu melhorar consideravelmente os resultados obtidos comparativamente à técnica tradicional, apontando novas possibilidades de investigação e aplicações nos laboratórios didáticos destinados a esta área do conhecimento. Tendo em vista que os vídeos produzidos podem e devem ser disponibilizados livremente na web, tornamos amplo e irrestrito o acesso e desenvolvimento de experimentos historicamente importantes, realizados apenas com equipamentos importados e de custo elevado. Acreditamos que a facilidade do método proposto somado ao custo zero, são aspectos facilitadores que torna este trabalho uma boa contribuição na ampliação do leque de possibilidades para a inserção de Física Moderna no Ensino Médio, uma preocupação permanente na área de Ensino de Física.
