This applet created by Prof Hwang
Modified by Ahmed

In the above simulation, there are six projectiles distributed uniformally.
Those 6 circles represent the initial positions (move with the earth) for those six projectiles.
Blue arrows shows the final displacement (you need to check displacement to see those blue arrows).
Two sets of six black traces are trajectories viewed from inertial/non-inertial frames.

In physics, the Coriolis effect is an apparent deflection of moving objects when they are viewed from a rotating reference frame. For example, consider two children on opposite sides of a spinning roundabout (carousel), who are throwing a ball to each other (see picture). From the children's point of view, this ball's path is curved sideways by the Coriolis effect. From the thrower's perspective, the deflection is to the right with anticlockwise carousel rotation (viewed from above). Deflection is to the left with clockwise rotation.

The Earth's surface is rotating fastest (in km/h) at the equator, and rotates not at all at the poles. A bird flying away from the equator, carries this faster motion with it (or, equivalently, the surface under the bird is rotating more slowly than it was)â€”and the bird's flight curves eastward slightly. In general: objects moving away from the equator curve eastward; objects moving towards the equator curve westward. A particle travelling east, would tend to follow straight on, lifting off in a plane perpendicular to the axis. The projection of that on the ground, to which the particle is bound by gravity and pressure, veers off towards the equator. Conversely, a particle moving west is overtaken by the groundspeed and pursues its straight course bending down towards the axis, sliding off towards the pole
