Coriolis force experiment demonstration instrument

Abstract

The invention relates to a coriolis force experiment demonstration instrument, belonging to the field of physical experiment equipment. The experiment demonstration instrument includes a rotary turntable mechanism, a power transmission mechanism, and a base support mechanism, the rotary turntable mechanism includes a rotary center shaft and a rotary disk, the power transmission mechanism includes a pinion, a bull gear, a speed regulation motor, and a fixing block, the base support mechanism includes a base and an adjustable support angle, the top of the rotary center shaft is provided with four particle inlets, the corresponding rotary center shaft under the four particle inlets is provided with inclined grooves in different angles, and the particles freely fall through the particle inlets at the same initial velocity and are rolled into the rotary disk after being accelerated through the different inclined grooves. The experiment demonstration instrument can visually demonstrate the offset of the particles in the linear movement in the rotary system relative to the rotary system due to the inertia, namely, the coriolis force existence phenomenon, so that the abstractness of conventional teaching material teaching can be improved, the teaching is facilitated, and the students can better understand the book knowledge.

Description

technical field

[0001] The invention relates to a Coriolis force experiment demonstration instrument, which belongs to the field of physical experiment equipment. Background technique

[0002] The full name of Coriolis force is Coriolis force, which is a description of the offset of the linear motion of the particle in the rotating system due to inertia relative to the linear motion generated by the rotating system. This inertial force, named after the French mathematician Coriolis who first studied it, is called the Coriolis force.

[0003] Physics is defined as a mass point moving in a straight line in a rotating system. Due to inertia, there is a tendency to continue moving along the original direction of motion. However, since the system itself is rotating, after a period of motion, the position of the mass point in the system will change, and the direction of its original motion trend, if viewed from the perspective of the rotating system, will deviate to a certain ext...
