Coriolis Effect - Behavior Of Objects Under The Coriolis Effect, History, Significance Of The Coriolis Effect
body force motion rotating
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.

Within its rotating coordinate system, the object acted on by the Coriolis effect appears to deflect off of its path of motion. This deflection is not real. It only appears to happen because the coordinate system that establishes a frame of reference for the observer is also rotating. The Coriolis effect is, therefore, linked to the motion of the object, the motion of Earth (the rotating frame of …
The Coriolis effect was first described by Gustave-Gaspard Coriolis, for whom the effect is named. Coriolis (1792–1843) was a French mathematician and engineer who graduated in highway engineering. He was a professor of mechanics at the École Centrale des Arts et Manufactures and later at the École des Ponts et Chaussées. Coriolis studied the motions of moving parts in …
The Coriolis effect is important to virtually all sciences that relate to Earth and planetary motions. It is critical to the dynamics of the atmosphere including the motions of winds and storms. In oceanography, it explains the motions of oceanic currents. Ballistics encompasses not only weapons but the motions of aircraft including launching and orbiting spacecraft. In the mechanics of machinery,…
