How to Maximize Kinetic Energy, Arrow Speed and Momentum


Maximize Kinetic Energy

A few seconds can make all of the difference between bagging large game and watching it scamper off into the woods. Using arrows possessing optimal momentum and speed will make each second count. It can boost your ability to get a clean kill and  improve odds of bringing home a trophy buck in your favor.

Successful bow hunters figure out which arrows will work the best for getting the work done before they head out to their favorite hunting grounds. Here are some things that you need to know to ensure you have the momentum and speed that you require for your arrows.

Bow Rate

Calculating your bow rate begins with knowing your bow speed rating. Many bows use an IBO specification. It follows that a bow is suppose to take an arrow that’s five grains per pound of draw weight. The bow is typically set at 70 pounds draw weight and 30 inches draw span with one nock set on the series. Variance can be plus or minus 3/4 of an inch at the draw span and plus or minus 2 pounds. From the draw weight. Some bows use an AMO specification.

These kinds of bows can be set to 50, 60 or 70 pounds of draw weight and a 30 inch draw length. Maximize Kinetic Energy variance is plus or minus 0.1 pounds. On the draw weight and 1/4 of an inch over the draw span. The bow has just 1 nock set on the series and demands an arrow that’s 5 grains per pound of draw weight. Despite the fact that bow ratings finish in 70 lbs., they usually shot at 60 pounds. This implies a bow will take at 3-to-4 feet per second slower with an arrow that’s five grains per pound draw weight.

Arrow Mass

An arrow’s effectiveness hinges on factors such as size, weight and arrow parts. Knowing these factors when establishing an arrow will enhance your bow’s capacity to do the job it’s designed to do. Arrows with more overall mass than an normal arrow will boost kinetic energy. It is possible to increase mass in numerous ways. 1 way is to decide on an arrow shaft with a greater weight per inch (GPI). Standard carbon arrows range 8 to 10 mph. Aluminum and carbon hybrid shafts will boost overall mass. Arrow mass is vital to raising lethalness and supplying wind drift resistance. An arrow which weighs from 420 to 450 grains supplies a wholesome balance between speed and Maximize Kinetic Energy.

Speed is not the only thing that matters in bow hunting. Maximize Kinetic Energy provides the power required to push an arrow through hide, bone and flesh and bring down your prey. Arrow rate and weight both affect the amount of kinetic energy generated when you shoot an arrow. Lighter arrows will increase speed at the expense of momentum. Which makes it more difficult to bring down larger game like a buck deer or bull elk.

The goal often is just wounded, requiring a followup shot which you may be unable to get off on time before it flees from range of your bow. Kinetic energy is just the energy of an object expended because of its mass and speed. You may compute kinetic energy within an arrow by carrying the weight in grains, multiplying it by the rate in feet per second squared and then dividing by the continuous 450800.


Momentum and kinetic energy isn’t the exact same thing. Both involve calculating mass and weight. The distinction with momentum is its energy retain as an arrow moves. Momentum is the energy necessary to prevent an arrow at a particular distance. Using a heavier arrow increases momentum as it is hard to stop the projectile after it meets resistance compare to a lighter arrow. This makes it far more deadly as it reaches the intended target.   A good guideline is to use an arrow with 6 grains of weight per pound for a 70 pounds. Rated bow, 8 grains for a 60 pounds. Rated bow and 10 grains for a 50 pounds. rated bow. Heavier arrows will function better in bringing down larger game. Such as deer and elk rather than merely wounding the creature and hammering it escaping.

How to Raise  Arrow Momentum and Penetration

Making an arrow effective in doing its job can be as straightforward as boosting penetration and momentum.   There are a couple of simple proven strategies you can use to achieve this objective.

  • Take a heavier shaft: With a rotating shaft that weighs 9 or 10 grains per inch, as an instance, will have higher penetration force on a lighter bow compared to one which weighs at 7 mph.
  • Shoot the appropriate backbone: Avoid using an arrow with a spine that is too soft to your bow. It’ll be too flexible in flight and slow penetration. Larger numbered spines mean more flexibility.
  • Take a heavier broadhead: Switching from 100 grain to 125 grain broadheads will raise the complete weight of the arrow and boost momentum.
  • Take a small-diameter shaft: Shafts comprising reduce diameter are more aerodynamic since they cut down on wind resistance. It may add inches of penetration than a heavier shaft with a larger diameter.
  • Take a cut-on-contact broadhead: This lessens the danger of the arrow not passing through sport, which may be an issue with some forms of mechanical broadheads. It means you will not need a follow-up shot to bring down game.

In case you’ve got the ideal amount of momentum and speed, your carbon arrows will have a flatter trajectory, better precision and deeper penetration. It all adds up to a more successful hunting trip.
