Matéria é tudo o que tem massa e que ocupa lugar no espaço. A partir desta definição chegamos a conclusão de que tudo aquilo que podemos pesar, medir, etc…, no universo ao nosso redor é matéria. Exemplo: as pedras, a madeira, água, o ar. Por outro lado observamos também que o som, a luz, o calor não são matéria. Constuma-se também dizer que: ”corpo é qualquer porção limitada de matéria”. A madeira como vimos é um exemplo de matéria, porém, um pedaço de madeira ou uma tábua, são exemplos de corpo. Um lápis ou uma mesa de madeira são exemplos de objeto. Energia Sabemos…

Fontes de Corrente: Ao estabelecermos um campo elétrico E-> num fio metálico– por exemplo, ligando as extremidades do fio aos polos de uma pilha ou de uma bateria – os elétrons livres existentes no fio, ficarão sob a ação de uma força elétrica. Como os elétrons são livres, eles entrarão imediatamente em movimento. O estabelecimento de um campo elétrico em um fio metálico provoca uma corrente elétrica. Também pode ser estabelecimento uma corrente elétrica em condutores líquidos. Consideremos, por exemplo, uma solução de NaCl. O sal dá origem a íons positivos (Na+) e aos íons negativos ( Cl-) que ficam livres e podem sofrer deslocamentos no interior do líquido. Ao se…
