Draw length is another factor of arrow speed. With a higher draw length, the arrow is affected by the bow for a longer distance. This results in faster arrows shot out of the bow.
Archers use different draw lengths, and higher draw length bows shoot faster arrows. I have everything you need to know there. The weight of the arrow is a major factor in its velocity.
If you use one bow, with the same setting, to shoot arrows with different grains, heavier arrows will end up slower. The reason is that the bow propels the arrow with the same amount of kinetic energy, which means a higher speed for lighter arrows. For the physics nerds, like me, the equation that describes the relationship between kinetic energy K , arrow mass m , and arrow speed v is:. The common numbers that describe the effect of arrow weight on arrow speed average at around 3 fps for every grain difference.
Using the equation above, though, you may be able to calculate more accurate numbers. Since IBO conditions use grain arrows, if, for example, you decide to use grain arrows, your arrows will be around 30 fps slower than the speed rating. For example, a more elastic material bowstring can transfer energy to the arrow more efficiently, resulting in higher speeds. The weight of the string matters as well, and the weight of the accessories on it.
This factor is a bit hard to quantify, though. Additional factors might include the design of the bow, lubrication of different components of the bow, and countless other elements. Most of these things are harder to measure and quantify, but you should be aware that they do play a role in the overall speed of your arrows.
As a general rule, faster arrows will have a flatter trajectory which lowers your margin of error, while heavier arrows can carry energy more efficiently and be more reliable. The real thing most bowhunters consider is the kinetic energy of the arrow, which in turn determines how much it can penetrate a target. Bigger targets require more penetration power, which means you need more energy to shoot them.

Finally, in addition to these factors, the distance an arrow can travel is also up to the skills of the archer. Most archers spend the bulk of their time doing target practice, whether they consider archery to be a sport or pastime. This is accomplished by shooting arrows at a target placed a certain distance away and attempting to hit the target with accuracy.
Archers develop their skills by working on improving their shooting distance and accuracy. Much of archery skill is about strength in drawing the bow, accurate aim, and smooth release of the arrow. These conditions create enhanced cast—momentum, speed, and distance—in launching the arrow from the bow. Modern, competitive archers often use carbon arrows due to their balanced weight and high strength which enhances distance. Whether archers fall into traditional , modern, competitive, or recreational categories, experts agree that the only way for an archer to know how far an arrow will fly is to shoot it.
This is why archers practice within the safety of archery ranges so that they can develop their form and technique, accuracy and distance. That can be left to the physicists. In archery, these primary factors are the type of arrow, external physical forces, and archer skill.
Skilled archers can understand these factors and use them in their favor to practice and further enhance their performance. One of the most appealing characteristics of archery as a sport and pastime is its connection with history, science, mythology, physical ability, and even modern culture. Those who wish to pursue archery to see how far they can shoot an arrow are in good company, as archery grows more popular each year.
I live in Alberta, Canada where I enjoy indoor and 3D archery with traditional bows and compound bows. So, what is the simple guide to know how far an arrow will fly? Arrow Properties In archery, there are three main types of arrows: wood, aluminum, and carbon. The properties of an arrow shaft greatly influence how far it will fly.
The weight of the arrow used is related to the construction of the bow; the heavier the bow, the heavier the arrow used to shoot.
Archers must consider arrow weight carefully, as heavier arrows move at lower speeds yet lighter arrows are less likely to penetrate targets. Strength: Each type of arrow has a different strength. When archers pull an arrow back against the string of a bow, the arrow gains potential energy.
The strength of an arrow is a combination of how well it withstands the kinetic energy and impact of the target. Arrow Material When specifying the material of an arrow, it refers to the make-up of the shaft or the long, hollow tube between the arrowhead point and nock the rear plastic tip that attaches to the string of the bow.
Here is a comparison of weight properties among the three main arrow types: Carbon fiber arrows are very light in weight which allows for consistent performance and good speed.
