# Dictionary:Coriolis acceleration

(kor, ē ō’ lis) **1**. A velocity-dependent acceleration in a reference frame that is moving with respect to an inertial reference frame. Specifically, the acceleration of a body in motion with respect to the Earth resulting from the rotation of the Earth, as seen by an observer on the Earth. The Coriolis acceleration on a body moving on the surface of the Earth with a velocity *V* is where =angular rotation of the Earth and is the latitude.
A Coriolis acceleration of a moving gravimeter is involved in the *Eötvös* *effect* (q.v.).
Named for Gustave Gaspard Coriolis (1792-1843), French mathematician.
