Problems solved by technology

[0002] The natural frequency of objects is the basic knowledge of physics. At present, in physics teaching, the natural frequencies of objects involved in physics are taught with the knowledge listed in textbooks. There is no physical teaching aid that demonstrates the natural frequencies of objects and other phenomena. To deepen students' understanding of what they have learned, can a physical teaching aid used to demonstrate the natural frequency of objects guide students to understand the relevant knowledge of the natural frequency of objects through the observed phenomena, thereby rapidly improving students' spatial imagination and using it It is a big problem for educators to understand and master the teaching content and effectively arouse students' interest in exploring scientific knowledge

Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with accompanying drawing example:

[0011] Such as figure 1 The physics teaching aid comprises base 1, and a suspender 2 is housed on this base 1, and sling 3 is housed at the end of suspender 2, and sling 3 is hoisted with a pendant, and this pendant has upper pendant 4, and upper pendant The top of 4 is provided with the connecting column 4-1 that links with pendant 4, and the joint of hanging rope 3 and pendant is located at the top of connecting column 4-1; The lower part is connected with two lower pendant parts 7 through two elastic connecting parts 6 .

[0012] During the experiment, put the physical teaching aid on the platform, adjust the excitation frequency of the micro-vibration motor 5 to the minimum, start the micro-vibration motor 5 and continuously change its vibration excitation frequency, and observe the movement of the two lower pendant parts 7 at the bottom of the upper ...

Abstract

The invention discloses a physical teaching aid, and relates to the technical field of teaching aid manufacture. The physical teaching aid comprises a base and a suspender arranged on the base. A pedant is suspended on the suspender through a lifting rope and provided with an upper pedant body with a miniature vibration motor, and the upper pedant body is connected with multiple lower pendulums through elastic connecting pieces at the bottom. Compared with the prior art, the physical teaching aid can be suitable for demonstrating various object inherent frequencies.

Description

technical field [0001] The invention relates to the technical field of manufacturing teaching aids, in particular to a physical teaching aid for demonstrating the natural frequency of objects. Background technique [0002] The natural frequency of objects is the basic knowledge of physics.
