What is the mechanics of javelin throw?
The mechanics of delivering the javelin are a summation of forces that begin from the ground and work up the body as energy is transferred from one body part to the next and ultimately into the spear. The analogy of “cracking a whip” is very descriptive of the action of the throw.
What is the aim of javelin?
Objective. The objective of Javelin Throw is to throw a spear-like structure (technically called as javelin) with your bare hands with maximum force so that it will land within a prescribed marking area.
What forces are used in javelin?
Center of Gravity and Pressure The center of pressure is the aerodynamic force of drag and lift on the javelin. The change in 1986 made javelins much easier to throw and much easier to measure because the center of pressure was moved back behind the center of gravity of the javelin.
Is javelin throw hard?
The javelin throw can be extremely strenuous and tough. At first glance, it may simply seem as if you are throwing a long rod; in reality, a lot of athletic ability and strategy go into throwing the javelin.
What are the stages of javelin?

How is javelin winner decided?
The javelin must also land tip first and within the marked 29-degree sector. If the tip touches the ground first, the throw is measured from this point. Athletes will commonly throw three or six times per competition. In the event of a tie, the winner will be the athlete with the next-best effort.
