The Coriolis force is a fictitious force exerted on a body when it moves in a rotating reference frame. It is called a fictitious force because it is a by-product of measuring coordinates with respect to a rotating coordinate system as opposed to an actual "push or pull."

This applet simulate particles motions observed from an inertia frame and rotating frame.
The spherical body will rotate when you press "play" button.
The red arrows are velocity vectors at different points on the spherical surface.
Press "jump" to shoot out particles.  
You can use mouse to change the 3D view.
