okay so ive been reading random stuff around the forum and i read some posts
saying that running away gives u more range or something like that. anyone care to
elaborate? does it mean as you are turning away from the opponent u gain range?

Utterly Wrong.

The error is that people are focusing only on the running away ship, but they have
forgotten the chasing ship.

Let's do some assumptions:

Gravity = -10m/s/s
Running ship = Ship 1
Chasing ship = Ship 2
Both ships have guns at max velocity which is 100 m/s
Both ships aim their guns at 45 degrees. (45 degrees is the optimum angle for max true range).
True range = the range of where the shells left the gun to where the shells land.
Effective range = the range of where the shells land to where the ship is at the moment of
landing.
Ship 1 velocity and Ship 2 velocity is the same = 10 m/s
The distance from ship 1 to ship 2 is 1km. (this is an arbitrary number but its easier for
the calculations)

Ship 1:

SOH CAH TOA

COS 45 = Adjacent/Hypotenuse
Hypotenuse is 100 m/s
100 * COS45 = Adjacent
Adjacent velocity is 70.71 m/s
Doing the same calculation with SOH, gives us the vertical velocity of also 70.71 m/s

Let's find out our hang time, vf = vi + at.
The time for a shell to get to the peak is calculated by setting the vf as 0. vi is our
initial vertical velocity which is 70.71 m/s. a due to gravity is -10 m/s. t is what we want.

0 = 70.71 + -10 * t.

t = 7.07 seconds.

Therefore total hangtime is 14.14 seconds.

Let's find out true range.

Using total hangtime 14.14 seconds, we multiply this to adjacent velocity, 70.71 m/s.

This gives us 999.8384 meters. About 1 km. Which is the same distance as the distance
between ships originally.

Let's find out our EFFECTIVE range.

Due the movement of the ship which is 10 m/s. Using total hangtimeof 14.14 seconds. 14.14
* 10 m/s gives us the distance the ship moved in the hangtime. Which is 141.4 meters.

Add 141.4m to the true range.

This gives us about 1141 meters.

Now minus 141.4 meters . Why? Because ship 2 has also travelled 141.4m.

Now you see the effective range is STILL 1km after 14.14 seconds. It STAYS the same.

Everything about ship 2 is the same except its firing in the opposite direction.

Now for some Einstein.

The speed of the shells relative to ship 1 and ship 2 is 70.71m/s. The speed however
relative to an non-moving observer is actually 60.71m/s for ship 1, and 80.71 m/s for ship
2. Remember that if ship 1 is moving forward and firing shells backwards, then adjacent
speed needs to decrease for an observer. Vice versa for ship 2.


A<--141.4m-->SHIP1<---999.8384m--->SHIP2

In 14.14 seconds, ship 1 moves to A. While ship 2 moves to B. (I haven't put B up because
it's hard to do in text).
B is basically 999.8384m - 141.14m = 857.86m
So point B is 857.86m east of where SHIP 1 was originally at.

What this all means is that SHIP 1 will hit SHIP 2.
AND
SHIP 2 will hit SHIP 1.

And all of this is due to relativity.

There are also further errors mentioned by some people, such as low angles or high angles
which are wrong aswell. If you want the most farther range ALWAYS aim at 45 degrees. That
is the most optimum range. The greater the velocity of the gun, the better.

The below will now confuse you unless you fully understood the above:

Now you all know why peps in Battlefield 2 do a run jump before throwing their grenades.
It gives them farther range.

The cool thing with relativity is that assuming a static target relative to YOU. If you
are a small ship with low range guns but high speed. By overheating and firing you can
extend your range by quite a bit. Assuming a NF guns with an average of 1000m/s and 45
degrees. Ships traveling at 60 knots can add an extra 30 m/s to the adjacent velocity.
That's 707m/s + 30m/s. That's an extra range of 4242 meters.

Savvy peps will now know there's a big problem. They've never seen shells hang for 14.14
seconds in NF.

You know why? Because NF doesn't implement true dimensions and physics. Since when was a
battleship the size of your thumb?

Running away doesn't give you more range.
Opponents chasing you give you more range.
Because shells have a hang time before they hit, the enemy ship will then travel towards
your shells, giving the effect of more range. If you look at where you shot from and where
your shells landed, however, they will be the same as any other shot.

I would also like to point out that low angle guns are better for chasing (because of
the less hang time they will reach the enemy ship faster and not allow much time for
the enemy ship to travel away)

and high angle guns are better for running, as the hang time is increased and
enemy ships will continue to move into the shots.

Range is not gained in any way its just the illusion since your ship is moving farther
away from where you shot so the shells still travel the same distance yet you moved away
which will add that much distance between you and where they land giving the illusion of
more range. It does still give an advantage if they chase you since the same affect is
working against them since they move towards the shots they fire.

Never noticed this before but the physics of how it works gives proof. Maybe that's why
when I did DD blitzing I hit crap better when they chased me. Great guide (ish thing). I'll
rec it tomorrow cause it's so nice to know.
