As bowhunters I feel we should focus about what KE our arrows have down range at the point of impact. Not when it leaves the bow. In flight, drag will cause the arrow to loose velocity (mass remains constant). I think that's where heavier arrows have an advantage over lighter ones, sure they fly slower, but don't,t loose as much speed in flight and have greater mass.

I have a 25 .5 " draw length and 60lbs draw weight and I shoot Easton fmj's and 125 grain fixed blade broadheads

Weight for quieting everything down is the biggest advantage! And it makes a huge difference! The most important thing on an arrow setup is a razor sharp broadhead. In the end, the kill factor is laceration.

I think you want to be pretty fast (260fps+) and pretty heavy (450+) and you'll be alright in almost every application. I currently have a Vertix with at 29.5" DL, 68lb dW, 500grain arrows and 275 fps average. Shooting a 125g fixed blade cut on contact. If you're mainly hunting white tail, even the shoulderblade is pretty punchable with a serious setup.

32” draw length and 68# draw... I wish there was a conversion without a chronograph so you know if it’s beneficial or can relax the weight, but knowing every bow is different. Looks like a trip to the archery shop!

This is a good video and has many good points , but the statement at 7:58 where it’s said that the weight increases the kinetic energy quicker than the velocity is actually incorrect. The formula for kinetic energy is k= 1/2 mv^2. This means that the velocity actually increases the kinetic energy quicker. This can be proved mathematically very quickly. Double the mass :1/2(2) (1)^2 = 1 Double the velocity: 1/2 (1) (2)^2= 2 This shows that velocity has a greater effect on kinetic Energy.

I’m trying to get my brother to Bowhunt with me . I told him how much fun it is and how much of a challenge it is . My question is for a new bow hunter , What is the best bow to start with ? My bow is a Hoyt Spider and I’m dialed in at 35 yards . Just asking for my brother if anyone has an idea just let me know thank you ! Also love your content ! Thank you and Bow Hunt or Die ! Good luck to everyone on the upcoming season!

The way I look at it kinetic energy is the factor important for getting the arrow to the animal and shooting flat, momentum is more important when it comes to driving through that animal with a broadhead. They are two similar things that are driven by different factors. Kinetic energy is more speed dependent and momentum is more weight dependent.

Thank you for the lesson

I’m a 27 in draw with 75 pound mods. Mathews v3. I shoot a 429 grain arrow 340 spine and around 290 FPS. I’m getting around 80 pounds of kinetic energy. When I start adding weight to my arrow and the speed decreases so does the kinetic energy. Guess that’s how it is with a shorter draw length! Lol

Wow! Your bow is really flinging those arrows well. Thanks for the great and informative video.

That helps understand it better

Such awesome advice on here! Thanks.

Thanks for the tip Big dawg 🤙

Good video I like how to videos bow set ups food plots also waiting for some trail camera pictures

Cool tec tip guys

It's nice to see someone who is not afraid to recommend heavier arrows over those puny, zippy things. Old time wisdom is finally making a comeback in the bowhunting world! Now, about all this electronic crap strapped to your bows....,.. next time.lol

(humbly new to hunting) basically, i have 2 arrows, mossy oaks and carbon express terminators, the oaks are 29inch 8.9 gpi, the expresses are 30 inch 11.3 gpi, i use 100g field tips and broadheads, im trying to decide if i should use the new terminators i got, take an inch off of the terminators and redo the inserts, add 5 more pounds to accommodate the higher gpi on the terminators, or simply go back to my mossy oaks, i want as much speed as possible, but without sacrificing kinetic energy, as i want clean pass throughs ( though for whitetail, isnt 53.2 enough for a passthrough anyway with a sharp fixed broadhead?) i just want to be efficient as possible, while getting the arrow to vitals in a timely manner without having to worry about wounding because of a string jump and a slightly slow arrow, any helpful constructive feedbacks or recommendations are all welcome and thank you kindly in advance. (Currently I shoot a Bear G2 Cruzer, don't know which setup to go between, i shoot a 55ib bow at 28inch draw length, the arrow stats are as follows;) Current setup: CE Terminators, .350 Spine, 30 Inch (55ib) (28Inch DL) Arrow Weight: 439g Arrow speed: 233.67fps Momentum: 2.026ns Kinetic Energy: 53.21 ft/ib Old Setup: Mossy oak Arrows, .350 Spine, 29inch (55ib) (28Inch DL) Arrow Weight: 353.3 Arrow speed: 262.6 (way Faster!) Momentum :1.826 Kinetic Energy: 53.92 Prospect (first arrow with an inch taken off) CE Terminators, .350 Spine, 29inch (55ib) (28Inch DL) Weight :427.7g Arrow Speed: 237.43 Momentum: 2.025 Kinetic energy: 53.53 2nd Option? Setup: (same Arrow as first but add 5ibs draw weight to my bow) (60ib) (28Inch DL) Weight: 439g Arrow Speed: 242 Momentum: 2.098 Kinetic energy: 57.08

You guys did great videos on “FOC” and “Kinetic Energy” now do one on “Momentum”. Break down SLUGS for us mouth-breathers.

Awesome video thanks brother

What is the model of that bow u were using it?

To gain more energy u have to draw more pounds my 406 grain arrows at 280 have 71 pounds of energy at 26.5 lenght arrows

There is no kinetic energy in a moving mass there is force Mv squared kinetic energy is the energy of consistent work from a consistent force regards Graham Flowers MEng

what is the arrow spine for your setup？

Your discussion of kinetic energy overlooks the fact that KE is calculated using the speed SQUARED, so KE is much more sensitive to changes in speed than to changes in weight. Also, bowhunters will tend to use their bow's advertised bow speed rather than its actual speed as measured by a chronometer. And even if they use a chronometer to determine the actual speed, it will be set quite close to the bow, where the archer is guaranteed to avoid hitting the chronometer itself. In either case, the arrow's speed will be considerably greater than its speed at the target, which is all that counts. So, I think your guidance here is quite misleading. Anyone familiar with firearm ballistics will have published tables showing projectile velocity at various down range distances, and will be well aware of how quickly velocity drops off. This, of course, affects both trajectory and downrange energy, and it's the downrange energy which must be taken into account when assessing the adequacy of any bow-arrow combination. Furthermore, you haven't mentioned at all what is probably the most important factor to consider - shot placement. A poorly placed shot, which is all too likely to result when the archer focuses primarily on factors like draw weight and kinetic energy, will NOT achieve a quick and humane kill. On the other hand, a well placed shot with equipment which on paper may seem inadequate, is much more likely to achieve success for the hunter in an ethical manner. Given the very slow velocities in archery compared with firearms, shot placement is extraordinarily dependent on reliable range estimation. I think you would have done much better to encourage hunters to practice their range estimating skills using a reliable laser rangefinder. Don't kid yourself that you can always use the rangefinder when hunting. The time taken to do so is time you will spend watching your prey bounding into the next county. Don't make the mistake of encouraging hunters to focus on aspects of "power". Far more important is having a bow you can handle easily and quietly, and being able to quickly and reliably estimate your range to target. Finally, let's not overlook the importance of keeping your broadheads razor sharp. If you're hoping to penetrate through hide and solid muscle on an animal that is fitter than any human athlete you've ever seen, blades that your buddy sharpened last season before they spent months bouncing around in your hunting kit are NOT going to cut it, either figuratively or literally.

You are very wrong. KE = 1/2*m*v². This is obvious, that v² is more important than m, because v is square.

Professor BHOD

Not true you don’t need 60 or 70 # many Hunters use 45 # and use a traditional bow and harvest many game animals look up the history Fred bear the father of bow hunting

Momentum is a better metric than kinetic energy at the muzzle - the force to keep moving

Question: How much intellectual “energy” does it require to shoot an arrow into an animal that is quietly minding its own business? Is there such a thing as less-than-zero “Failed-Male” energy? You know…as in a Trump supporter? Thank you!
