Coriolis Effect

The Coriolis effect is a mechanical principle demonstrating that, on a rotating solid body, an inertial force acts on the body at right angles to its direction of motion. The Coriolis effect (also called the Coriolis force) is based on the classic laws of motion introduced to the world by Sir Issac Newton (1642–1727). A rotating body not only moves according to Newtonian motion, but it is also acted on by an inertial force. If that body is rotating in a counterclockwise direction, the inertial force will deflect the body to its own right with respect to the observer. If the body is rotating in a clockwise motion, the inertial force acts to the left of the direction of motion.
