Embodiment Construction

[0019] Such as figure 1 The shown physics classroom teaching aid includes three hollow rings 101 , 102 , 103 forming a bracket 100 . Each hollow ring is equipped with a hollow pipe 201, 202, 203, wherein the first hollow pipe 201 extends from the highest point of the first hollow ring 101 to the lowest point of the first hollow ring 101 along the diameter, the first Two hollow tubes 202 extend from the highest point of the second hollow ring 102 to the ring of the second hollow ring 102 along the direction of an angle of 30° with the diameter, and the third hollow tube 203 extends from the third hollow The highest point of the ring 103 extends to the ring of the third hollow ring 103 at an angle of 45° to the diameter. A small ball release device 300 is respectively provided at the intersection of the three hollow rings 101 , 102 , 103 and the three hollow tubes 201 , 202 , 203 at the highest point, and a small ball 400 is respectively installed in the small ball release devi...

Abstract

The invention discloses a physics teaching aid, comprising a bracket composed of three hollow rings, each of the hollow rings is provided with a hollow pipe, wherein, the first hollow pipe extends to the bottom point from the top point of the first hollow ring along the diameter, the second hollow pipe extends to the second ring from the top point of the second hollow ring along the direction which presents a 30 DEG angle with the diameter, the third hollow pipe extends to the third ring from the top point of the third hollow ring along the direction which presents a 45 DEG angle with the diameter, the junctions of the three hollow rings and the three hollow pipes at the highest points are respectively provided with a small ball release device, and the small ball release devices are respectively provided with a small ball. The teaching aid has function of demonstrating principle of 'isotraveling time circle', and has advantages of improving the understanding of the principle of 'isotraveling time circle' for students.

Description

technical field [0001] The invention relates to a physics classroom teaching aid, in particular to a physics classroom teaching aid for verifying the "isochronous circle" principle. Background technique [0002] The subject of physics is highly theoretical, and some difficult knowledge points are often not easy for students to understand. In order to facilitate students' understanding, teachers usually use some teaching aids to demonstrate. [0003] In the actual teaching process, the inventor found that many students could not solve the related exercises of "isochronous circles", which shows that students have difficulties in understanding the principle of "isochronous circles". Such as figure 1 Example questions shown: [0004] "ad, bd, and cd are three fixed smooth thin rods in the vertical plane, a, b, c, and d are located on the same circle, point a is the highest point of the circle, and point d is the lowest point. Each rod is set There is a small slip ring (not sh...
