Flat Earth Q&A / Re: The Coriolis effect and snipers.
« on: June 07, 2009, 03:33:54 AM »I'm not talking about the effects seen on the path of a projectile, I'm sure they exist. I'm talking about scientifically determining causality.
Snipers have to compensate for it, but they don't have to actually know the mechanisms behind it in order to adjust their aim. Why would they?
Why should they? They know the earth is rotating to the east, that means they need to compensate for it, because once their bullet leaves the barrel, it no longer rotates along with the earth. Since your "reference frame" is rotating the bullet path seems curved.
bridget, I'm done with you. You haven't said anything of any effect. The so called "Gyroscopic drift" is different from the Coriolis effect, and for long range artillery it has no significant effect. (2 inches lol)

The Coriolis effect causes drift related to the spin of the Earth, known as Coriolis drift. Coriolis drift can be up, down, left or right. Coriolis drift is not an aerodynamic effect. It is a result of flying from one point to another across the surface of a rotating sphere (Earth). For small arms, this effect is generally insignificant, but for ballistic projectiles with long flight times, such as extreme long-range rifle projectiles, artillery and intercontinental ballistic missiles, it is a significant factor in calculating the trajectory.
The coordinate system that is used to specify the location of the point of firing and the location of the target is the system of latitudes and longitudes, which is in fact a rotating coordinate system, since the Earth is a rotating sphere. During its flight, the projectile moves in a straight line (not counting gravitation and air resistance for now). Since the target is co-rotating with the Earth, it is in fact a moving target, relative to the projectile, so in order to hit it the gun must be aimed to the point where the projectile and the target will arrive simultaneously. When the straight path of the projectile is plotted in the rotating coordinate system that is used, then this path appears as curvilinear. The fact that the coordinate system is rotating must be taken into account, and this is achieved by adding terms for a "centrifugal force" and a "Coriolis effect" to the equations of motion. When the appropriate Coriolis term is added to the equation of motion the predicted path with respect to the rotating coordinate system is curvilinear, corresponding to the actual straight line motion of the projectile. For an observer with his frame of reference in the northern hemisphere Coriolis makes the projectile appear to curve over to the right. Actually it is not the projectile swinging to the right but the earth (frame of reference) rotating to the left which produces this result. The opposite will seem to happen in the southern hemisphere.
The direction of Coriolis drift depends on the firer's location or latitude on the sphere, and the azimuth of firing. The magnitude of the drift depends on the location, azimuth, and time of flight. The Coriolis effect is at its maximum at the poles and negligible at the equator of the Earth. The reason for this is that the Coriolis effect depends on the vector of the angular velocity of the Earth's rotation with respect to xyz - coordinate system (frame of reference).

Of course.
The Soviet tactics plans are all in the local library. I live in an ex-Socialist republic.
The Coriolis effect is in wiki. If you trust wiki on Angular momentum, or drift or w/e, you must trust it on Coriolis.

So your argument is based on your faith in the accuracy of reported statistics from the US government's military divisions? Obviously, there are many factors that offset the long range accuracy of a projectile, and until we can eliminate the influences of all but one we can't scientifically determine causation.
How about the ex Soviet and Chinese government? Are they in cahoots with NASA as well?
What about the Democratic People's Republic of Korea? They all compensate for this effect.

I am not an "alt", Bridget. The moderation team may check my IP address, even call my ISP. I never been on here, as far as I remember. Also, it would be nice to know how I "admitted" to be an "alt".
...that is of course if "alt" means alternative account. I prefer the term "sock puppet", but "alt" seems good too.
Now will you please explain how the Coriolis effect fits with the stationary flat earth?

Also, the gyroscopic drift deflects the projectile with an insignificant amount. 23 inches to 1.90 inches, depending on the weight of the projectile.
In artillery, 23 inches don't matter. The Coriolis effect is a massive deflection.
Where did you come up with these figures? And 'massive' is such a quantitative term.
The table in Wikipedia.
I used "massive" because it sounds dramatic.
Still, look at the link you posted, there you will find how much projectiles get deflected.

Why does it seem curved then?
Also, artillery rounds are spin stabilized only initially after which fins are deployed to stabilize it. (US Patent - 4460137)

I'm talking about the Coriolis effect that's taken consideration in high range artillery and sniper shots during wars...
You're trying to jack the topic somewhere else.
Explain why all artillery takes the Coriolis effect into consideration if the earth isn't rotating?

Call of Duty would be a good example if it weren't created by the BLASTED CONSPIRATORS!

What's the Coriolis effect?
It is an apparent deflection of moving objects from a straight path when they are viewed from a rotating frame of reference. In layman's terms, it means that long range fire (artillery shells and sniper rounds) will not appear to fly in a straight line from the shooter to the target because of the rotation of the Earth on its axis. Rather, the round or shell will appear to curve. In actuality, the shot is flying in a straight line but the turn of the Earth moves the target so it will look as if the round or shell is curving. Artillery gunners and snipers are well-trained to compensate for the Coriolis effect by actually not aiming directly at their target, but off to the side so that by the time the bullet makes it to the target distance, it has "curved" to hit the target.
Ask any military personnel from any country, any hunter, enthusiast shooter, everyone is going to confirm the Coriolis effect.
The above proves the earth is rotating, putting a deep wound in your theory.

Air does not influence radio waves in any way, except for slowing them down.

Wait, I see your point... lol
Still, I just need to get one thing straight.
If you accelerate an object, i.e. throw a ball and there's nothing resisting that acceleration, will the ball continue its acceleration constantly?
RoundEarth420, 9.8 m/s? is not velocity.

If there's no air resistance to the object, then the object should appear as floating.
If you accelerate an object and there is nothing to stop it, that object will retain its speed constantly until infinity.
