Abstract
The utility model discloses a circumferential centered motion experiment teaching aid for physics teaching. The teaching aid comprises a support frame, a concave skewed slot, a ball body, a transparent circular track, a microprocessor, a liquid crystal display and a speed sensor. One side of the support frame is fixedly provided with the transparent circular track. The ball body is arranged in the concave skewed slot. An exit end of the concave skewed slot is connected with an entry end of the transparent circular track. The concave skewed slot is opened upwardly. An entry section of the transparent circular track is provided with the speed sensor. An output end of the speed sensor is connected with an input end of the microprocessor. An output end of the microprocessor is connected with the liquid crystal display. The teaching aid intuitively demonstrates the centrifugal movement to students by visual teaching means, and verifies the minimal speed enabling a small ball to generate a centrifugal force by arranging the speed sensor at the bottom, and is simple to operate, vivid and interesting in teaching experiment, and convenient to popularize.
Description
Technical field
The utility model relates to a kind of physics teaching teaching aid, refers more particularly to a kind of physics teaching centripetal exercise testing teaching aid of circumference.
Background technology
At present, the circular motion experiment does not also have special teaching experiment teaching aid in senior middle school physics teaching, generally to be imparted knowledge to students by oral account or diagram by the teacher, because there is no experiment teaching aid, impart knowledge to students visual in image not, the student understands difficulty, memory is shallow, although some teacher adopts some Self-made Realia to carry out teaching demonstration, but teaching aid is lack of standardization, is difficult to popularize.
The utility model content
The purpose of this utility model provides a kind of physics teaching centripetal exercise testing teaching aid of circumference with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
the utility model comprises bracing frame, the spill skewed slot, spheroid, the transparent ring track, microprocessor, liquid crystal display and speed pickup, one side of support frame as described above is fixed with described transparent ring track, described spheroid is arranged in described spill skewed slot, the endpiece of described spill skewed slot is connected with described transparent ring track entrance point, the groove mouth of described spill skewed slot up, the entrance point of described transparent ring track is provided with described speed pickup, the output terminal of described speed pickup is connected with the input end of described microprocessor, the output terminal of described microprocessor is connected with the input end of described liquid crystal display.
Particularly, the endpiece of described transparent ring track is provided with gets the ball box, and the described ball box top of getting is provided with baffle plate.
Particularly, the ramp height of described spill skewed slot is greater than the diameter of transparent ring track.
The beneficial effects of the utility model are:
The utility model, by the teaching means of image, shows the student with centrifugal motion intuitively, and by being arranged on the speed pickup of bottom, the checking bead can produce the minimum speed of centripetal force, has simple to operately, and the education experiment vivid and interesting, be convenient to promote.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-spill skewed slot, 2-transparent ring track, the 3-speed pickup, 4-baffle plate, 5-are got the ball box, 6-bracing frame, 7-liquid crystal display, 8-spheroid.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
as shown in Figure 1, the utility model comprises bracing frame 6, spill skewed slot 1, spheroid 8, transparent ring track 2, microprocessor, liquid crystal display 7 and speed pickup 3, one side of bracing frame 6 is fixed with transparent ring track 2, spheroid 8 is arranged in spill skewed slot 1, the endpiece of spill skewed slot 1 is connected with transparent ring track 2 entrance points, the groove mouth of spill skewed slot 1 up, the entrance point of transparent ring track 2 is provided with speed pickup 3, the output terminal of speed pickup 3 is connected with the input end of microprocessor, the output terminal of microprocessor is connected with the input end of liquid crystal display 7.
as shown in Figure 1, the endpiece of transparent ring track 2 is provided with gets ball box 5, get ball box 5 tops and be provided with baffle plate 4, the ramp height of spill skewed slot 1 is greater than the diameter of transparent ring track 2, spheroid 8 is from the peak of spill skewed slot 1 take initial velocity as zero release (the ring pipe center that the height at spheroid 8 centers pushes up slightly higher than transparent ring track 2 when doing Physical Experiment, be that the height at spheroid 8 centers is less times greater than 2R), when spheroid 8 enters transparent ring track 2 along 1 rolling of spill skewed slot, the speed pickup 3 that is arranged on spill skewed slot 1 bottom detects the speed of spheroid 8 and by showing on liquid crystal display 7 after the microprocessor analog-to-digital conversion, the peak (moving in a circle) that spheroid 8 almost can arrive top on transparent ring track 2 shows the student with centrifugal motion intuitively, checking spheroid 8 can produce the minimum speed of centripetal force.
These are only preferred embodiment of the present utility model,, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all should be included in protection domain of the present utility model.
