The Coriolis force demonstration device of the utility model discloses the principle of a river scouring the river bed on one side. The problem to be solved by the utility model is how to demonstrate repeatedly that in the same rotating inertial system, a linear moving object is acted by Coriolis force and deviates from the straight line movement, and reveals the phenomenon of the river scouring the river bed on the earth on one side. The main technical point is that the turntable is composed of a turntable, a low-speed motor, a bearing and a base. The utility model has the following advantages: 1. It can clearly and low demonstrate the phenomenon that a linear moving object in a rotating inertial system deviates from the direction of linear motion and moves in a curve under the action of Coriolis force. The deviation direction is related to the rotation direction of the inertial system and the motion direction of the object; 2. In the rotating inertial system, the phenomenon that the ball moves in a straight line in the groove and rolls along the groove unilaterally reveals the principle of the river on the earth scouring the river bed unilaterally; the utility model also has the characteristics of simple structure and simple operation.
