What effect does friction have on javelin?
Friction can affect the javelin's speed and distance by slowing it down as it travels through the air. A smoother surface on the javelin reduces air resistance and friction, allowing it to travel further. Ultimately, reducing friction can lead to better javelin performance.
How do they measure the distance a javelin is thrown?
The distance a javelin is thrown is measured from the point where the javelin first strikes the ground to the nearest mark made by the point of the javelin that remains in the ground. The measurement is then taken in a straight line from the first mark to the throwing line.
How is a javelin throw measured if does not stick into the ground?
If a javelin does not stick into the ground, the throw is measured from the point where it first strikes the ground to the nearest edge of the curve made by the javelin. This method ensures a fair measurement of the distance thrown, even if the javelin does not stick into the ground.
How does fluid force effect the trajectory of the javelin?
Fluid force can affect the trajectory of a javelin by creating drag, which is resistance that opposes the motion of the javelin through the air. The greater the fluid force, the more drag the javelin will experience, leading to a deviation from its intended trajectory. Athletes may need to adjust their technique to minimize the impact of fluid forces on the javelin's flight path.
Can a slow object travel as far as a fast object?
Yes, a slow object can travel as far as a fast object given enough time. The distance traveled depends on the speed of the object and the duration of its travel.
