Javelin

A slender throwing implement with a pointed metal head, cord grip, and shaft, designed to fly point-first when thrown.

Javelin throw: A track-and-field event in which athletes throw a javelin for distance. The implement is designed specifically for this athletic throwing event.
Javelin grip: The cord-bound section of a javelin where the athlete holds it. This is the implement’s designated handhold and a key part of its release.
Spear: A pole weapon with a pointed head, designed for thrusting or throwing. The javelin belongs to the broader family of pointed throwing weapons.
Javelin throw technique: The sequence of movements athletes use to accelerate and release a javelin. Technique converts the athlete’s approach and arm action into javelin speed.
Javelin redesign: Changes to javelin specifications intended to alter flight and landing behavior. Competition javelins were redesigned to reduce distances and improve the likelihood of point-first landings.
Center of mass: The point representing the average position of mass in a body or system. Its position helps determine the javelin’s balance and flight behavior.
Drag coefficient: A dimensionless quantity describing an object’s resistance to fluid flow. Drag affects how quickly the javelin loses speed in flight.
Javelin hunting: The pursuit of game using a thrown javelin or similar spear. Hunting is among the practical uses that preceded the javelin’s modern sporting role.
Javelin throw rules: The regulations governing valid attempts and equipment in the javelin throw. Rules constrain the implement’s construction and how a throw must be executed.
Javelin throw landing rules: The criteria for deciding whether a javelin throw lands legally. A throw counts only when the javelin’s metal head strikes the ground first.
