A javelin is a long, slender spear-like object used in track and field athletics, specifically in the javelin throw event. It is designed to be thrown by an athlete with one hand, aiming to cover the greatest distance possible. The javelin is typically made of metal or fiberglass and has a pointed tip at one end for smooth, aerodynamic flight. The length and weight of the javelin vary slightly depending on the competition, but it is generally around 2.5 meters long for men and about 2.2 meters for women. The design allows it to fly through the air in a straight or slightly curved path when thrown properly.
