Coriolis acceleration is an acceleration dummy can be seen when an object moves on a platform that is moving. From the standpoint of the observer in the rotating reference system, the object is curved and deviates from its path. However, for an outside observer, the object describes a straight line.
The video clearly shows this effect:

Earth is a rotating platform and Foucault, in 1851, built a large enough pendulum to see how his plane was diverted oscillation ( because it made the surface of the Earth). A Foucault pendulum describe a complete turnaround in 24 hours if we were located at the poles. In other latitudes the angular velocity of the pendulum is proportional to the sine of the latitude (in Ecuador the pendulum does not deviate).
