Which of the following bows features limbs that sweep back and forward at the tips, giving it more potential energy?

The recurve bow is designed with limbs that curve away from the archer when unstrung and curve back toward the archer at the tips once it is strung. This unique design allows the recurve bow to store more energy in the limbs compared to a straight-limbed bow, such as a longbow. As a result, when the bowstring is released, the limbs snap back to their original position, resulting in increased velocity and power of the arrow. This makes the recurve bow particularly effective for hunters and archers who need both speed and accuracy in their shots. The ability to produce greater potential energy contributes to its popularity in various archery disciplines, including target shooting and hunting.

In contrast, other bows mentioned do not offer the same limb design that enhances energy storage and performance. The crossbow, while powerful and accurate, operates on a different mechanism and is not characterized by limbs that bend in the same manner. The longbow has a more straightforward design lacking the dynamic limb curvature that facilitates energy storage. Traditional bows, which may encompass various designs, do not necessarily have the recurve feature that boosts potential energy. Thus, the recurve bow stands out for its unique ability to enhance performance through its specific limb structure.
