A "bow" is a curved weapon used for shooting arrows. It consists of a flexible material, often wood or fiberglass, and a string that connects its two ends. When the string is pulled back, it stores energy, which is released when the string is let go, propelling the arrow forward. Bows have been used for hunting and warfare throughout history. In addition to its use as a weapon, the term "bow" also refers to a gesture of bending at the waist as a sign of respect or greeting. This action is often seen in various cultures, such as in Japan where it is a traditional form of greeting.
