Uma comparação entre deduções da equação E=mc²

Abstract: Recebido em 07/01/04; Aceito em 02/03/04Neste trabalho, apresentamos quatro deduções conhecidas da equação E = mc 2 , incluindo a original. Relacionamos os conceitos físicos e as ferramentas matemáticas utilizados em cada caso e comparamos as deduções. Após a análise, verificamos que três deduções são acessíveis ao estudante do Ensino Médio. Palavras-chave: Relatividade Especial, equivalência massa-energia.In this work, we present four known deductions of the equation E = mc 2 , including the original. We rela… Show more

“…In such a way, a particle, although at rest, has the energy that is associated with mass. "So we have to replace the classic conservation laws, separately from mass and energy, with a single law of conservation of total relativistic energy: the total relativistic energy of an isolated system remains constant" [27].…”
