The major advantage of a higher draw weight bow is that the arrow trajectory is flatter. 105 results for bear bow parts. The Bear Facts With Bow and Arrow Part I and II by. Light Arrows: Downrange Speed and Power. The instant that an arrow leaves the string, it is at its maximum velocity and will immediately start to slow down. Light Arrows, a Discussion of Arrow Deceleration. Arrows achieve velocity as the bow is drawn (energy added by the archer) then released (energy transferred from the bow limbs through the string and to the arrow.) At the instant an arrow leaves the string. Light Arrow Flight. In this section we are going to take a deeper look into the physics and math behind what is happening after an arrow leaves the bow. We will start with the very basic equation that was briefly mentioned above: F=m*a. In our case the area is the same, the density of air is the same and of course the coefficient of drag is the same. Light Arrow Flight. This part of the article is going to deal with the real world numbers when a light arrow is shot vs. The Bear Facts With Bow And Arrow Part I And Ii CrimesBy measuring the speed of different arrows at various distances, it is easy to calculate which arrow maintains more of its speed and thus its kinetic energy and momentum farther downrange. Introduction and archery equipment for testing. Test equipment for this round of shooting. If you care about all of the math and the theory behind how arrows decelerate after leaving the bow, please make sure to read all of the above article first. For this testing, I’ll be using two arrows that are virtually identical to each other on the outside, but one will be weighted with an extra shaft and weight layered on the inside. These first numbers come from using two Victory VForce HV arrows, one standard that weighs in at 3. The heavier arrow also has additional weight on the inside near the point in order to keep the FOC of both of the arrows nearly identical. Both arrow use FOBs for the fletchings. All arrows were shot from my Elite Envy set at 2. All of the speeds in each set were within +/- 0. Results of arrow speed testing. Speed (fps)KEMomentum. Change from 0 Yards. Grains. 0 Yards. 31.

The actual testing results follow what would be expected from the theory and math discussed earlier. I would like to test the speeds out to further distances and will do so in the future to get a better picture of behavior downrange. It’s interesting to see just how much more the lighter arrow slows down and sheds its kinetic energy and momentum. The lighter arrow is losing speed at a rate 4. At point blank range, the heavier arrow starts with 3. I would say that is a significant difference! Of course the extra KE and momentum come at a cost, trajectory. The heavier arrow is going to drop significantly more at every distance and yardage estimation becomes much more critical. A three to five yard mis- judgement in yardage with the lighter arrow could still result in a clean kill shot on an animal, while with the heavier arrow it most likely would result in a much poorer shot or even perhaps a complete miss. That being said, having a fast arrow is no substitute for practice in yardage estimation or using a range finder when possible. Each archer needs to know their own equipment and make their own decisions on arrow weight depending on the game being hunted and where they are hunting. Know your equipment and practice with it constantly! Future testing. In the future I plan on doing testing out to forty or more yards, and also with some lighter and heavier arrows. I have some 2. 62 grain Speed Pro Max arrows donated to the cause that should be fun to play with (yes, I will be shooting them at 6. I will also use some different types of fletchings (4.
