Utility model content
The purpose of this utility model is, a kind of demonstration teaching aid that potential energy is changed into kinetic energy is provided, with the simple structure of its cheap cost, completes on-the-spot Physical Experiment, above-mentioned theory is demonstrated out intuitively, make learner can watch study in any teaching environment, thereby improve the quality of teaching.
For realizing above-mentioned purpose of the present utility model, provide following technical scheme:
Design the demonstration teaching aid that a kind of potential energy transforms kinetic energy, for above-mentioned physical phenomenon is carried out to teaching demonstration, its structure member comprises: the end points that is connected respectively slope guide rail and horizontal guide rail by the two ends of column, and another end points of slope guide rail is connected with the middle part of horizontal guide rail, formation, with the triangular structure of right angle of extended line, has completed the basic framework of described teaching aid with its simple structure; The horizontal guide rail of the upper surface of slope guide rail and described right-angle triangle extended line part forms slideway and upper surface is groove type low between edge senior middle school; And indicate length mark to show the shift length of object in its outside; For demonstration object provides on the spring pedestal that the spring of elastic potential energy, one end be arranged on described horizontal guide rail end and parallel with described horizontal guide rail; Potential energy transforms the spherical that the carrier of kinetic energy is certain mass, can by high potential energy or elastic potential energy, by it, release or the release after described spring is compressed in guide rail upper end, described slope is converted into kinetic energy; The carrier of demarcating kinetic energy is cylindrical body, at described spherical, along being advanced into described horizontal guide rail under the guide rail of described slope or clashing into this cylindrical body after described spring ejecting, makes it along the described horizontal guide rail kinetic energy of certain distance to show that it is obtained that moves ahead.
Preferably, for preventing that spherical from occurring secondary impact after colliding with cylindrical body, the face that is knocked of described cylindrical body is the high, normal, basic concave surface in limit.
Preferably, described horizontal guide rail itself and guide rail junction, described slope and and described vertical pillars junction between upper surface portion stylobate be set fixedly and be permanent magnetic material.
Preferably, described spherical is that permeability magnetic material is made, and place or be attracted to during carrying on described fixedly stylobate and unlikely being scattered, and described spherical is set by a certain percentage in himself quality when a plurality of at this teaching aid.
Preferably, one end of described cylindrical body is with permeability magnetic material, place or be attracted to during carrying on described fixedly stylobate and unlikely being scattered, and described cylindrical body set by a certain percentage in himself quality when a plurality of at this teaching aid.
The utility model simple in structure and low in cost, can be under all teaching environments in mode intuitively, to beginner, demonstrate the physical phenomenon that potential energy is converted into kinetic energy, and for the kinetic energy of object and the size of its initial potential energy and sole mass this physical law that is directly proportional has provided test basis, thereby raising learning quality.

Embodiment
The specific embodiment of the demonstration teaching aid of a kind of potential energy conversion kinetic energy described in the utility model as shown in Figure 1, this teaching aid is connected respectively the end points of slope guide rail 2 and horizontal guide rail 3 by the two ends of column 1, and another end points of slope guide rail 2 is connected with the middle part of horizontal guide rail 3, formation is with the triangular structure of right angle of extended line, the upper surface of the horizontal guide rail 3 of the upper surface of slope guide rail 2 and described right-angle triangle extended line part is groove type low between edge senior middle school, to form the slideway part of this teaching aid, side mark long measure scale 31 distances in order to 5 displacements of display column's body of horizontal guide rail 3, and thereby horizontal guide rail 3 end positions are equipped with spring pedestal 41 and are provided elastic potential energy in order to mounting spring 4 for spherical 6, quantity as the cylindrical body 5 of kinetic energy carrier is one, and to experiment, bring error for preventing secondary impact, the face that is knocked of cylindrical body 5 is designed to the high, normal, basic concave surface in limit, the spherical 6 that potential energy transforms kinetic energy carrier is three, and sole mass arranges by a certain percentage, the tie point of column 1 and horizontal guide rail 3 is arranged with fixed station base 32 to the upper surface portion of the horizontal guide rail 3 between slope guide rail 2 and the tie point of horizontal guide rail 3 and provides riding position for cylindrical body 5 and spherical 6, because containing permanent magnetic material, fixing stylobate 32 can make the cylindrical body 5 and the spherical 6 that contain permeability magnetic material be adsorbed in, thereby unlikely being scattered when carrying, the agent structure of this teaching aid adopts the cheap materials such as wooden or metallic, therefore with low cost.
The demonstration teaching aid that a kind of potential energy described in the utility model transforms kinetic energy is when demonstrating, spherical 6 can be taken off to the top that is placed in slope guide rail 2 from fixing stylobate 32, cylindrical body 5 is placed on to the initial place of the long measure scale 31 on horizontal guide rail 3, discharging spherical 6 makes it under the effect of high potential energy, after slope guide rail 2 rolls into, enter horizontal guide rail 3 downwards, now the high potential energy of described spherical 6 be zero and kinetic energy for maximum, in the initial place of long measure scale 31, clashing into cylindrical body 5 makes it to stop after horizontal guide rail 3 is done translation, the length of cylindrical body 5 its translations of clashing into respectively same quality with the spherical 6 of different quality is thereupon different, after in like manner discharging with spherical 6 Compress Springs 4, clashing into cylindrical body 5 makes it along horizontal guide rail 3, do to stop after translation, the translation length that compression degree difference is knocked rear cylindrical body 5 is also just different, thereby the high potential energy of object and the physical phenomenon that elastic potential energy is converted into kinetic energy have been demonstrated, also for big or small this physical law that is directly proportional to the size of its initial potential energy and sole mass of object kinetic energy provides experimental basis.
In sum, the utility model has been realized the object of object teaching with its succinct cheap cost of structure compact to design, and convenient carrying, is particularly suitable under the simple and crude teaching environment of condition, implementing demonstration, has effectively improved quality of instruction.
