The answer of mine is "Yes". I have reasons about that. First, on the bow, there is a rubber string. And the rubber has an elestic force. When we push the string, then the elestic force works, the rubber wants to be the shape before. So when we release our hand, the arrow flies. Second, we make the arrowhead streamlined shape. So the air resistance that flying arrow has decrease. Thank you for reading this and for doing my class, teacher Maryl^_^ 답변자 tc0135 답변일 2013-06-05 답변내용 The writer's question in the article was, "Is there a scientific principle here(archery)?"
