What Causes an Arrow to Fly?
It is caused by the power generated when you bend the bow and string of the bow and arrow out of shape. The bow and string have the quality of elasticity which causes a rubber ball to bounce. When you force anything elastic out of shape, this quality in it makes it try to get back to its natural shape quickly. In doing this it acts in the direction which will take it back to its normal shape most quickly. The arrow is fixed on the string in a way that will not interfere with the bow and string getting back to its shape and, when they bounce back, the arrow goes with it. The real cause for the arrow’s flight, however, comes not from the bow, because the bow cannot put itself out of shape, but comes from the person who causes it to be out of shape and, therefore, the person who pulls the string back really causes the arrow to fly.
