Abstract

The invention provides a coriolis acceleration demonstration instrument used for demonstrating a coriolis acceleration phenomenon and calculating coriolis inertia force. The coriolis acceleration demonstration instrument is characterized by comprising a coriolis acceleration demonstration member used for demonstrating the coriolis acceleration phenomenon, a coriolis inertia force measuring member which is connected with the coriolis acceleration demonstration member and is used for measuring magnitude of the coriolis inertia force, and a supporting member used for mounting the coriolis acceleration demonstration member. According to the coriolis acceleration demonstration instrument and a coriolis inertia force measuring method, magnitude of the coriolis inertia force is indirectly measured through an equivalent substitution method, so a problem of difficulty in measuring the coriolis inertia force can be settled, and a coriolis acceleration calculation formula can be further verified.

Description

technical field [0001] The invention relates to a teaching tool, in particular to a Coriolis acceleration demonstrator capable of verifying the Coriolis acceleration formula and a method for measuring the Coriolis inertial force by using the Coriolis acceleration demonstrator. Background technique [0002] The Coriolis acceleration is the acceleration caused by the mutual coupling between the rotation of the moving reference system and the motion of the moving point relative to the moving reference system. Coriolis acceleration is an important knowledge point in theoretical mechanics, and it is also a difficult point for students to understand. Students are often at a loss when learning Coriolis acceleration, and teachers are also very difficult to teach. The root cause of this phenomenon lies in the abstract nature of Coriolis acceleration. Therefore, if the teacher can use teaching aids to demonstrate the phenomenon of Coriolis acceleration and calculate the size of the C...
