Well i just switched to a lighter arrow. Im shooting a 500 spine lightspeed easton arrow with a 60Gr. tip on it! I think your slower but heavier arrow will hit a little harder at a shorter distance but the lighter faster arrow will carry more Kinetic energy farther. Im a firm believer that it all equalls out. Everyone has an opinion though. If you hit them where your suppose to you will not have any problem with any set up!
The highlited sentence is COMPLETELY false. A HEAVY arrow will retain it's speed and KElonger, because it has more momentum. Here's a simple way to explain it....Go outside, and find 2 small rocks. 1 of those 2, a tiny pebble, the other your average sized rock you would find on a driveway. Now throw them both, I PROMISE that you'll throw the heavier "arrow" farther.
Edited for spelling....darn typos...
So what your saying is that if your shooting a 450 gr arrow at 270fps and i was shooting a 300 gr arrow at 320fps your arrow is gonna hit as hard if not harder at 50 yards as mine?
Absolutely. These are just laws of physics, not anything I'm pulling out of thin air. A heavy arrow will not slow down as fast, thus retaining it's KE longer than a light arrow? Why? Because it had more to start with, and, it's not slowing down as fast.
The formula for KE is speed x speed x weight / 450240. If KE is directly related to weight and speed, and the heavy arrow has more KE to start with, AND retains it's speed longer......You do the math, no way the light arrow can keep up. Laws of physics....It CAN'T....
Go back to the rock. It's the same principle.....Which one goes farther? The heavy one, I guarantee it.
Go back to my arrows......355 grain arrow, flying 318 = 79 pounds of KE.
490 grain arrow, flying 282 = 86 pounds of KE, AND it won't slow down as quickly. Which one has more downrange energy?
Im not trying to be difficult here by no means...just learn. I understand your physics and all but it does not sound correct. Ok back to your rocks if one weighs 20 pounds and one weighs 5 pounds and you shooot them the one weighing 20 pounds is traveling 100fps. the one that is 5 pounds ia traveling 300fps i dont see the bigger rock going farther nor do I see it maintaining its speed as long thus dropping quickly to the ground!
Ohwell if im shooting an animal at 50 yards I would want light and fast-vs- slow and heavy. Thats just me Ive never had a problem with my arrows sticking in the dirt and if they are in the dirt you got plenty of penetration!
LOL.....well......the 5 and 20 pound rock really isn't a good example, because the average person isn't capable of throwing a 20 pound rock very far.....but I promise it will hurt more if you get hit by it....
Look back at my numbers. The heavy arrow has more KE right at the start.....it's a law of physics that it won't slow down as fast, so how is the light arrow going to have more down range energy?? Stop for a second, and think about it. Where is the light arrow going to catch up at? If it's slowing down faster, and had more KE to begin with....where will the light arrow make up for it?? It simply can't.
Let's say the heavy arrow, flying 282, is flying 272 at 30 yards. Now, the light arrow slows down faster, again...law of physics, cannot be refuted....it's a proven FACT. So, the light arrow is that was flying 318 is now flying 303 fps.....do the math.
490 grain arrow, at 30 yards, = 80.5
350 grain arrow, at 30 yards, = 71.3
See?? Those are fictitious speeds, but they are close. I slowed the heavy arrow down 10 fps, thelight arrow 15.
I'm sure someone w/ on target software can give exact speeds here, but those are close. There is simply no way the light arrow can make it up...
