Abstract
The utility model discloses a demonstration device for curvilinear moving direction. The demonstration device has the main structure which is formed by the vertical delta connection of a support frame, a horizontal base and an oblique slot track, wherein the lower end of the oblique slot track is processed with one to four annular tracks in sequence. The annular tracks are fixed on the horizontal base in vertical direction. Different positions on the annular tracks are provided with cut sections which are respectively provided with arc-shaped track blocks. When the demonstration is carried out, a small ball rolls down from the top end of the oblique slot track and the small ball moves along the oblique slot track and the annular tracks in sequence. When one arc-shaped track clamp arranged on one annular track is removed, one cut section is formed on the annular track, at the moment, the small ball can roll down from the top end of the oblique slot track again and then the small ball can fly out in tangential direction from the cut section along the annular track. Thus, the utility model can clearly display the speed direction of the motion of small ball along the annular tracks and the motion along tangential direction at the cut sections. The demonstration device for curvilinear moving direction has the advantages of simple structure, easy use, convenient operation and visual demonstration. The utility model provides a good physics teaching apparatus.
Description
Technical field
The utility model relates to the demonstration instrument that a kind of physics teaching is used, and refers in particular to demonstrate to make the instrument of curvilinear motion object at diverse location place velocity reversal.
Background technology
At present, in the middle school physical experiment class, do not see the instrument that to demonstrate object curvilinear velocity direction.And when teaching, the teacher does the velocity reversal of curvilinear motion in order to explain object, and the globule that the edge is thrown out during usually with watering dish or umbrella rotation illustrates the velocity reversal of object curvilinear motion.Also useful cord hauls the bead rotation, and after cord was slipped out of the hand, bead direction of motion was velocity reversal.But the movement locus direction of the globule and bead often is not easy to see clearly.It is very necessary developing a kind of energy instrument clear, that demonstrate object curvilinear velocity direction intuitively.
The utility model content
The technical problems to be solved in the utility model provides a kind of curvilinear motion direction demonstrator, and this demonstrator object can be done the velocity reversal of curvilinear motion and movement locus is clear, demonstration is intuitively come out, to reach teaching efficiency well.
Technical matters of the present utility model is solved by following scheme: curvilinear motion direction demonstrator, it is characterized in that: described demonstrator is formed by connecting by support, horizontal base and the vertical triangle of skewed slot track, the lower end of skewed slot track is made 1～4 ring ring successively, and ring ring vertically is fixed on the horizontal base.
Technical matters of the present utility model also comprises following scheme: the diverse location place has section on the described ring ring.The arc track card is equipped with at section place on the described ring ring respectively.The both sides of described skewed slot track are the edge that exceeds.The both sides of described ring ring are the edge that exceeds.The both sides of described arc track card are the edge that exceeds.
The utility model has the advantages that: simple and reasonable, movement locus comes into plain view.During demonstration, bead is rolled down from skewed slot track top, bead promptly flies out along skewed slot track, ring ring motion successively.As the arc track card of adorning on the ring ring is got the next one, promptly formed a section on the ring ring, at this moment again bead is rolled down from skewed slot track top, bead i.e. tangential direction from section along ring ring flies out.Equally also can be in other position repetitive operation.Like this, just be clearly shown that bead at ring ring section place along the velocity reversal of tangential motion with along the track of whole circular motion.Curvilinear motion direction demonstrator is easy to use, easy operating, demonstrating visual, is a kind of good physics educational apparatus.

Fig. 2 is the stereographic map (ring ring takes off the track card) of this curvilinear motion direction demonstrator
Embodiment
As shown in Figure 1, curvilinear motion direction demonstrator is formed by connecting by vertical support 1, horizontal base 2 and skewed slot track 3 vertical triangles, and the lower end of skewed slot track 3 is made 2 ring rings 4 successively, and ring ring 4 all vertically is fixed on the horizontal base 2.
As shown in Figure 1, on 2 ring rings 4, respectively open 1 section 5, and 6 connections of arc track card respectively are housed at section 5 places.The both sides of skewed slot track 3, ring ring 4 and arc track card 6 all have exceed along 7.Between support 1 and horizontal base 2 and the skewed slot track 3 all is that hinge is connected.During demonstration, bead is rolled down from skewed slot track 3 tops, bead is promptly successively along skewed slot track 3, ring ring 4 motions.At last, bead is from tangentially oblique the dishing out of ring ring 4 ports 8.
As shown in Figure 2, as the arc track card 6 of dress on the ring ring 4 is got the next one, promptly form section 5 on the ring ring 4.At this moment bead is rolled down from skewed slot track 3 tops, promptly 4 tangential direction flies out bead from section 5 along ring ring again.
Claims (6)
1, curvilinear motion direction demonstrator is characterized in that: described demonstrator is formed by connecting by support, horizontal base and the vertical triangle of skewed slot track, and the lower end of skewed slot track is made 1～4 ring ring successively, and ring ring vertically is fixed on the horizontal base.
2, curvilinear motion direction demonstrator according to claim 1, it is characterized in that: the diverse location place has section on the described ring ring.
