Speed vs. cast

[owlbait]

Can/will a bow that shoots slower cast an arrow farther? Why or why not? This question came up on another thread. Thanks for help clearing this up.

NO. the same projectile at a higher rate of speed will go a longer distance if shot at the same angle. There is really no arguement as it is simple ballistics. If two projectiles that are identical are started at exactly the same time and shot straight down the one that is shot from the more efficient weapon will arrive first. even if they are both going the same speed due to wind resistance when they hit the ground. The more efficient weapon imparts more of its energy into the projectile. This is why a 40 lb bow that is super efficient can outshoot a 50 lb bow that is mediocre./

God bless and hope this helps, Steve

Nope, cant. 2 identicle arrows, the faster one will go farther.

32 fps/second is an immutable fact that can't be gotten around.

Thank you. Thanks to Chuck C for his help also.

Well if the faster arro isn't properly tuned to the bow or the bow tiller isn't proper.Why wouldn't a bow w/ proper arro tunning and tiller that's a few feet slower cast a arro further?

As I understand it, cast was used in bow performance tests before chronographs were readily available.

It's OK to talk about cast but the 's' word upsets a lot of the older crowd.

lol

yep,..they are integral parts of the same equation.

Why is Speed such a controversial word here on TG?

Not trying to stir up dust but it puzzles me. Part of the accuracy, I get, is due to speed equaling cast.

So true, so true. Especially with the trad police.      :p

Trouble is in the details. You just cannot have one without the tother. We can introduce mitigating factors such as ballistic coefficiency but when all test projectiles are equal the fastest projectile at the start of the race goes the farthest.

God bless you all, Steve

Old Timers...  

Back in the late 60's when I started shooting and bowhunting, when someone said "This bow has good cast"...same as saying the bow has decent speed.

Then someone would throw a monkey wrench in the mix and state "My 50# bow is capable of casting an arrow 150 yds."  We took that to mean the bow was designed well. So....to answer your question...
Depends on the angle the bow is held....

Unless physics change anytime soon... and barring any outside interference... the above is the only way a slower arrow will travel farther than a faster one shot at the same angle.

Okay, let's say the projectiles aren't fired straight down, but perfectly parallel to the ground.  One projectile is 25% heavier than the other, but is only 10% slower, which one will go farther?  Been too many year since I use physics, but doesn't momentum enter into the equation?

[kawika b]

Remember that gravity is pulling more on that heavier arrow.

[Sixby]

Selfbow: that just changed the question completely. This is no different than adding in the question of ballistic coefficient. A fair test would have to be done with identicle projectiles if it is to be valid at all.

God bless you all, Steve

Sixby,

The original question was "Can/will a bow that shoots slower cast an arrow farther?" I tried to put the question in terms we all deal with, e.g., will my heavy slower arrow, go further than your lighter faster arrow?  The real answer is, it depends!!  We're not talking a perfect vacuum, sans gravity.  The original question did not mention shooting straight down.  If shooting straight down, wouldn't distance and terminal velocity come into play? At some point, as I recall, gravity controls the velocity of a "falling" (shooting straight down) object.
