Ответ:
Esses movimentos são movimentos naturais.
Explicação:
Se uma pedra cair do topo de um telhado ou edifício, a pedra se moverá em direção à terra, enquanto a fumaça produzida devido à queima da madeira vai para cima, então de acordo com Aristosteles esses tipos de movimento são chamados de movimento natural porque de acordo à definição de movimento natural que não requer nenhuma força, então esses dois movimentos também se movem na direção para baixo e para cima sem usar qualquer força, então podemos dizer que esses movimentos são naturais.
