Física aristotélica

"The concept of violent motion had its difficulties, for the pushes and pulls responsible for it were not always evident. For example, a bowstring moved an arrow until the arrow left the bow; after that, further explanation of the arrow's motion seemed to require some other pushing agent. Aristotle imagined, therefore, that a parting of the air by the moving arrow resulted in a squeezing effect on the rear of the arrow as the air rushed back to prevent a vacuum from forming. The arrow was propelled through the air as a bar of soap is propelled in the bathtub when you squeeze one end of it."
Tirei essa parte do livro de física conceitual do Hewitt (não achei em português, foi mal) e fiquei com um pé atrás da orelha
Não sei se interpretei corretamente, mas no experimento dos planos inclinados de Galileu, Aristóteles não poderia argumentar que é essa força do ar quem manteria o movimento indefinidamente, em vez da inércia?
