A bow is a flexible arc that shoots aerodynamic projectiles called arrows. A string joins the two ends of the bow and when the string is drawn back, the ends of the bow are flexed. When the string is released, the potential energy of the flexed stick is transformed into the kinetic energy of the arrow. Archery is the art or sport of shooting arrows from bows.
