Abstract
The invention relates to the technical field of teaching materials. As is well known, in existing teaching tools in schools at present, a used research device of a pendulum is single in function, teaching is influenced to a certain degree, and the used research device of the pendulum is inconvenient to use nor ideal. In order to overcome the defects, the invention provides a multifunctional pendulum research device, and the purpose of facilitating the teaching can be achieved. According to the technical scheme for solving the technical problems, the multifunctional pendulum research device is composed of a base, a direction coordinate, a pendulum length quantification marker post, a protractor, a dangling transverse rod and a pendulum bob. The multifunctional pendulum research device is characterized in that the pendulum length quantification marker post is arranged on the base which is provided with the direction coordinate, and the protractor and the dangling transverse rod with the pendulum bob are arranged on the pendulum length quantification marker post. Therefore, pendulum deflection and amplitude can be clear at a glance in teaching, and the purpose of facilitating the teaching can be achieved. The multifunctional pendulum research device has the advantages of being simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of teaching material class technical field.
Background technology
At present, known in school, in the existing teaching aid, the research device function ratio of the pendulum of use is more single, and teaching is had certain influence, and is very inconvenient, also not ideal.
Summary of the invention
In order to overcome above-mentioned deficiency, the invention provides a kind of multi-functional pendulum device that grinds, just can reach the purpose of convenient teaching.
The technical scheme that the present invention solves its technical matters is: the multi-functional pendulum device of being made up of base, direction coordinate, the quantitative mark post of pendulum length, protractor, dangle cross bar and pendulum that grinds, it is characterized in that: the base that is provided with the direction coordinate is provided with the quantitative mark post of pendulum length, and the quantitative mark post of pendulum length is provided with the cross bar that dangles of protractor and band pendulum.Like this, when teaching, the amplitude of oscillation and amplitude all can both come into plain view, thereby reach the purpose of convenient teaching.
The invention has the beneficial effects as follows: simple in structure, easy to use.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present invention.
1. bases among the figure, 2. direction coordinate, the 3. quantitative mark post of pendulum length, 4. protractor, cross bar, 6. pendulum 5. dangle.
Embodiment
Among Fig. 1, the base 1 that is provided with direction coordinate 2 is provided with the quantitative mark post 3 of pendulum length, and the quantitative mark post 3 of pendulum length is provided with the cross bar 5 that dangles of protractor 4 and band pendulum 6.Like this, when teaching, the amplitude of oscillation and amplitude all can both come into plain view, thereby reach the purpose of convenient teaching.
