Abstract
The utility model discloses a single pendulum frequency and pendulum length experimental instrument. The single pendulum frequency and pendulum length experimental instrument is characterized by comprising a substrate made by a bottle cap, a vertical rod arranged above the substrate and made by a pen holder, a non-fixed lower horizontal rod arranged on the vertical rod and an upper horizontal rod fixed at the end side of the upper part of the vertical rod, wherein the single pendulum is arranged at the central side position of the upper horizontal rod, a small hole is arranged at the central side of the lower horizontal rod and the single pendulum passes through the small hole. The single pendulum frequency and pendulum length experimental instrument disclosed by the utility model is made by materials such as a plastic pen holder, a plastic bottle cap, daily necessities and the like which can be easily found around students, and therefore the production cost is low; as the experimental instrument is simple in structure and easy in making, the experimental instrument is suitable for the students to make, the learning enjoyment of the students is enhanced and the practical ability of the students are trained; and the physical phenomenon is intuitive and clear.
Description
Technical field
The utility model relates to the teaching and experiment equipment technical field, is specifically related to a kind of single pendulum frequency and pendulum length experimental apparatus.
Background technology
Adopt flexile form of teaching, allow the student easier, get more information about the thought that has embodied modern teaching with learning knowledge, especially in the elementary and middle school teaching in period, because some scientific knowledge, concept are more abstract, dry as dust, add the vivaciously active of student, for a long time sustained attention power, so adopt flexile happy teaching method, be conducive to excite student's desire for knowledge and consolidate the knowledge of acquiring.In now teaching; usually can allow the student get more information about and learn the knowwhy of single pendulum hunting frequency and pendulum length by some experiment equipments; but the knowwhy of some single pendulum; be difficult to find fixing experiment equipment; and some experiment equipment is expensive, also is no small input concerning some schools, and the few of interest of some experiment equipment itself; student couple is not high with the enthusiasm of experiment, takes exercise limited to student's manipulative ability.
The utility model content
It is a kind of convenient and practical that technical problem to be solved in the utility model is to provide, and can excite student's scientific exploration interest, improves single pendulum frequency and the pendulum length experimental apparatus of students ' practical ability.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of single pendulum frequency and pendulum length experimental apparatus, it is characterized in that: comprise the pedestal made from bottle cap, be located at the montant that the pedestal top makes with penholder, be located at the revocable sheer pole on the montant, be located at the distolateral fixing cross tube in montant top, the middle side position of described cross tube is provided with a single pendulum, and the middle side of described sheer pole is provided with an aperture, and described single pendulum passes aperture.
Described single pendulum comprises cycloid and swing ball.
The left side of described sheer pole is provided with circular hole, sheer pole by circle hole sleeve on montant.
The beneficial effects of the utility model are: the utility model is easily to look for material at one's side with the student, and plastic penholder, plastic bottle closure, commodity etc. are made, and cost is low; Experiment instrument is simple in structure, and it is easy to make, thereby suitable student's manual fabrication, has increased student's study enjoyment, has tempered student's manipulative ability; Physical phenomenon is simple and clear.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of single pendulum frequency and pendulum length experimental apparatus, comprise the pedestal 1 made from bottle cap, be located at the montant 2 that pedestal 1 top makes with penholder, be located at the revocable sheer pole 3 on the montant 2, be located at the distolateral fixing cross tube 4 in montant 2 tops, the middle side position of cross tube 4 is provided with a single pendulum 5, the middle side of sheer pole 3 is provided with an aperture 6, and single pendulum 5 passes aperture 6, and single pendulum 5 comprises cycloid 51 and swing ball 52.The left side of sheer pole 3 is provided with circular hole 7, and sheer pole 3 is enclosed within on the montant 2 by circular hole 7, and sheer pole is moved up and down.
When single pendulum 5 swings, when moving up and down sheer pole, to estimate as can be known, the length that single pendulum 5 cycloids 51 swing can change, and the frequency that single pendulum 5 swings also changes thereupon, thus the hunting frequency when understanding single pendulum 5 swings and the relation of pendulum length.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
