Description
Technical field
The present invention relates to a kind of demonstrator, specifically is a kind of novel Physical Experiment demonstrator, belongs to the teaching aid technical field.
Background technology
In physics teaching in secondary school, the classification of power has many kinds, but there is certain difficulty in the actual understanding, therefore need help the intelligential effect of student by the demonstration of experiment, at present, the demonstrator that adopts is to experimentize by naked eyes and manual operation, not only waste of manpower, and also there is certain deviation in the inaccurate student of making of experimental result in the understanding of friction force.
Summary of the invention
The invention provides a kind of novel Physical Experiment demonstrator, have automatic force, the effect of environmental protection and energy saving.
To achieve these goals, the technical solution used in the present invention is: a kind of novel Physical Experiment demonstrator, comprise fixed base plate, wooden unit, cord, dynamometer, display screen, the serving machine, bracing frame, motor, housing and solar panel, wooden unit is arranged on the fixed base plate, cord is fixedlyed connected with wooden unit, serving machine and motor are fixedly connected on the bracing frame, solar panel is arranged on case top, display screen and dynamometer are arranged in the housing, solar panel is electrically connected with motor and dynamometer respectively, dynamometer is electrically connected with display screen, and the serving machine is electrically connected with motor.
The invention has the beneficial effects as follows: simple to operate, easy to use, environmental protection and energy saving help the student and understand.
Description of drawings
Fig. 1 is a structural representation of the present invention
Among the figure: 1, fixed base plate, 2, wooden unit, 3, cord, 4, dynamometer, 5, display screen, 6, the serving machine, 7, bracing frame, 8, motor, 9, housing, 10, solar panel.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes fixed base plate 1, wooden unit 2 and cord 3, it is characterized in that also comprising dynamometer 4, display screen 5, serving machine 6, bracing frame 7, motor 8, housing 9 and solar panel 10, wooden unit 2 is arranged on the fixed base plate 1, cord 3 is fixedlyed connected with wooden unit 2, serving machine 6 and motor 8 are fixedly connected on the bracing frame 7, solar panel 10 is arranged on housing 9 tops, display screen 5 and dynamometer 4 are arranged in the housing 9, solar panel 10 is electrically connected with motor 8 and dynamometer 4 respectively, dynamometer 4 is electrically connected with display screen 5, and serving machine 6 is electrically connected with motor 8.
During use, motor 8 is started working, motor 8 drives serving machine 7 and starts working, serving machine 7 drives wooden unit 2 by cord 3 and carries out uniform motion, and dynamometer 4 calculates, by observing display screen 5, can see the size of friction force this moment, solar panel 10 is for the invention provides electric energy.So just can make the student clearly understand the generation of friction force.
