# What is the Coriolis effect regarding snipers?

I'm looking for a definition.

 +1 vote! +7 you voted Answer by  gibin (9) A fictitious force sometimes used to simplify calculations involving rotating systems,such as the movement of air,water,and projectiles over the surface of the earth. The concept was first used in 1835 by Gaspard de Coriolis(1792-1843),a French Physicist. The Coriolis force is the force that a native observer thinks is needed to push the air eastwards.

In layman's terms, the earth is rotating and the Earth is also not flat. From your perspective the Earth is not moving and is also flat. You only need to factor Coriolis effect in sniping when it is at extremely long distances.

The reason is that the moving mass, when seen from the non-rotating reference frame, is moving in a straight line - but that line is not straight if seen from someone who's rotating while it's being drawn!
