Coriolis Force

Yesterday I promised you an explanation of Coriolis Force. After searching in the internet, I could find some definition about it. There are:

1. A fictitious force used to explain a deflection in the path of a body moving in latitude relative to the earth when observed from the earth. The deflection (Coriolis effect) is due to the earth's rotation and is to the east when the motion is towards a pole.

2. Velocity-dependent pseudo force which is mathematically used to describe the motion of bodies in rotating reference frames such as the Earth's surface. Bodies moving on the plane of rotation appear to experience a force, leftward if the rotation of the reference frame is clockwise, rightward if counterclockwise. Such motion gives rise to the Coriolis effect.

3.An apparent, rather than real, force which causes the deflection of moving objects, especially of air streams, through the rotation of the earth on its axis. It shows up, for example, in the movement of an air stream, relative to the rotating earth beneath it.

So, you can make the conclusion on your own way, cant you?? :D
