Description
Technical field
The utility model relates to a kind of teaching aid, specifically a kind of kinetic energy potential energy converting and energy demonstrator.
Background technology
Senior middle school physics curriculum, in explanation kinetic energy potential energy converting and energy, explain that the minimizing of potential energy can cause the increase of kinetic energy to student, otherwise the minimizing of kinetic energy can cause the increase of potential energy, can mutually change between the two.Classroom teaching uses now animation model and data are calculated the process of having explained to a certain extent kinetic energy potential energy converting and energy, but owing to there is no demonstration instrument intuitively, student is difficult to understand, simultaneously, due to directly hands-on, be difficult to improve student's learning interest.
Summary of the invention
The purpose of this utility model is to provide a kind of strong kinetic energy potential energy converting and energy demonstrator simple in structure, easy to use, interesting, drills intuitively the rule of kinetic energy potential energy converting and energy, helps student to grasp well scientific knowledge wherein, improves student's learning interest.
The utility model for the technical scheme that technical solution problem adopts is:
Kinetic energy potential energy converting and energy demonstrator described in the utility model comprises the riser being vertically mounted on base, be fixedly mounted on the track on riser, described track comprises horizontally disposed horizontal rail, vertically disposed vertical track and be connected to horizontal rail and vertical track between arc track, above described horizontal rail, be provided with horizontal opening groove, in described horizontal opening groove, be slidably fitted with horizontal baffle, in the inner chamber of horizontal rail, be provided with spring, described spring is connected between horizontal baffle and the end cap of horizontal rail, the upper end of horizontal baffle extends to the outside of horizontal rail, the upper end of horizontal baffle fixedly mounts horizontal paintbrush, described riser is provided with the horizontal drawing board corresponding to horizontal paintbrush, the sidewall of described vertical track is provided with vertical openings groove, slide plate is connected on riser by vertical track, on slide plate, by horizontally disposed chute, positioning baffle is installed, the front end of described positioning baffle extends to by vertical openings groove in the inner chamber of vertical track, one side of described slide plate is installed with vertical paintbrush, and described riser is provided with the vertical drawing board corresponding to vertical paintbrush.
Adopt after technique scheme, this demonstrator structure is simple, easy to use, interesting strong, can drill intuitively the rule of kinetic energy potential energy converting and energy, and can be directly by student's hands-on, help student to grasp well scientific knowledge wherein, improve student's learning interest.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the A-A cut-open view of Fig. 1 embodiment.
Embodiment
As shown in Figure 1, kinetic energy potential energy converting and energy demonstrator described in the utility model comprises the riser 2 being vertically mounted on base 1, be fixedly mounted on the track on riser 2, described track comprises horizontally disposed horizontal rail 3, vertically disposed vertical track 4 and be connected to horizontal rail 3 and vertical track 4 between arc track 5, above described horizontal rail 3, be provided with horizontal opening groove, in described horizontal opening groove, be slidably fitted with horizontal baffle 6, in the inner chamber of horizontal rail 3, be provided with spring 7, described spring 7 is connected between horizontal baffle 6 and the end cap of horizontal rail 3, in horizontal baffle 6 slides in horizontal opening groove, spring 7 is compressed.The upper end of horizontal baffle 6 extends to the outside of horizontal rail 3, the upper end of horizontal baffle 6 fixedly mounts horizontal paintbrush 8, described riser 2 is provided with the horizontal drawing board 9 corresponding to horizontal paintbrush 8, when moving with horizontal baffle 6, horizontal paintbrush 8 can on horizontal drawing board 9, draw line segment, for capable of reducing friction resistance as far as possible, horizontal paintbrush 8 adopts soft writing material as writing brush etc.
As shown in Figure 1 and Figure 2, the sidewall of described vertical track 4 is provided with vertical openings groove, and slide plate 10 is connected on riser 2 by vertical track 11, and slide plate 10 can be slided up and down in the vertical direction.On slide plate 10, by horizontally disposed chute, positioning baffle 12 is installed, positioning baffle 12 is inserted in the chute of slide plate 10, and can slide in the horizontal direction, the front end of described positioning baffle 12 extends to by vertical openings groove in the inner chamber of vertical track 4, one side of described slide plate 10 is installed with vertical paintbrush 13, and described riser 2 is provided with the vertical drawing board 14 corresponding to vertical paintbrush 13.In the time that vertical paintbrush 13 moves with slide plate 10, can on vertical drawing board 14, draw lines.In order to reduce frictional resistance, vertical paintbrush 13 adopts the soft writing implements such as writing brush equally.
When use, heavy ball 15 is placed on positioning baffle 12, raises slide plate 10, now vertical paintbrush 13 draws lines on vertical drawing board 14, and the top of lines is exactly the initial position height of heavy ball 15.Extract positioning baffle 12 out, discharge heavy ball 15, after heavy ball 15 falls, enter horizontal rail 3 along arc track 5, promote horizontal baffle 6 Compress Springs 7, and on horizontal drawing board 9, drawing lines by horizontal paintbrush 8, the position of this lines least significant end is exactly the maximum compression scope of spring 7.
While oppositely demonstration, operator promotes horizontal baffle 6 Compress Springs 7, and horizontal baffle 6 is shifted onto to the least significant end of the lines that horizontal paintbrush 8 draws, by heavy ball 15 be put into horizontal baffle 6 before, emission levels baffle plate 6, spring 7 ejects heavy ball 15, and enters vertical track 4 along horizontal rail 3, by positioning baffle 12 and slide plate 10 jack-up, simultaneously vertical paintbrush 13 draws lines on vertical drawing board 14.
Owing to there being certain frictional resistance, the slightly difference of four line segments that 2 paintbrushes of forward and reverse operation draw, but difference is very little, ignores under the prerequisite of frictional resistance impact, the terminal position of both sides operation middle conductor is consistent, so just can prove intuitively the mutual conversion of kinetic energy and potential energy.
