The Coriolis Force

It is caused by the rotation of the earth.

That is, if the Earth were not rotating there
would be no Coriolis Force.

Also, if there were no wind, there would be no Coriolis Force

The Coriolis force can only deflect air that is already in motion. It cannot put an air parcel in motion.

Get it now?

wind has no effect, this would happen in a vacuum...

in short: don't. Video games don't calculate the coriolis force into the trajectaries of objects. Though irl you should know what direction you're shooting in. If you're shooting to the east or west, there's no effect. If you're shooting to the north the bullet will appear to bend to the left, to the south it will appear to bend to the right. So if your target is north of you, aim right of his head. If he's south of you, aim left of his head. Be aware the effect is small over small distances.

You're in the northern hemisphere in CoD4 and therefore the bullet will go to the left. In the southern hemisphere, it's opposite.

Thanks a lot - was waiting for this.

does th force work without gravity or air?

Gravity is another fictitious force that acts on a body in a non-inertial frame of reference (like the Coriolis force).

The best way you can "see" a pure force is when there is only that force that is acting on a body. So the Coriolis force would be more predictable if there wasn't air drag and friction (friction is due to gravity).

But be careful because fictitious force do not always obey the Newton's 3rd law (read about quantum mechanics).

Diff question. It's not a force...
It stands loose of gravity and air and w/e. But it is not a real force, the ppl on the wheel are just in an accelerating frame of reverence (thus a non-inertial one). That means the laws of newton don't apply there. The force is just an operator you apply to all objects in order to acheive an inertial frame of reference, thus getting a system where the laws of newton are valid, but strange things appear to happen.

this video is confusing..try watching another one because the ball seems to curve when ur watching from above...

Eum no, this video isn't confusing at all. Watch the guy in yellow passing the ball. The ball follows a perfect straight line from 0:03 to 0:04. Watch it again, because you missed it.
