Detailed description of the invention
Embodiment one
See accompanying drawing 1, it is structural representation of the present utility model.Vertical upthrow demonstrator, comprise the first vertical track 1, the second vertical track 2, and the 3rd track 3 of circular arc, it is characterized in that: the lower end of the first track 1 is fixedly connected with a upper end of arc-shaped rail 3, the lower end of the second track 2 is fixedly connected with another upper end of arc-shaped rail 3, and the first track 1, second track 2, the 3rd track 3 are in smoothing junction
And the first track 1, second track 2, the 3rd track 3 are in same plane, and this plane orthogonal is in base 4 place plane,
The bottom of the 3rd track 3 is fixedly connected with base 4, and the end 4 is provided with the screw rod 8 for adjusting base level,
Also be provided with the electromagnet 5 removably connected with the first track 1,
Also comprise and inhaling below electromagnet 5, for the iron ball along described first track 1, the 3rd track 3, second orbital motion 2,
Second track 2 is provided with for determining the weight line 7 whether the second track 2 is vertical,
And the shape of cross section of the first track 1, second track 2, the 3rd track 3 is circular arc.
Using method: rotary screw 8, allows base 4 for horizontal plane, and whether use weight line to observe the second track 2 vertical, if not vertical, adjustment screw rod 8, makes the second track 2 be positioned at vertical direction.Be energized to electromagnet 5, attract iron ball 6, then disconnecting circuit, iron ball 6 along orbital motion, then will be gone out from the vertical upthrow in top of the second track 2.How to adjust screw rod 8 and belong to prior art, various equivalent modifications should be known, and this product of weight line 7 is not thin piece of string, but fine rule and the weight general name after being connected, weight line 7 belongs to prior art.The position of adjustment electromagnet 5, just can change the initial velocity of vertical upthrow, namely changes the end speed of iron ball 6 at the second track.
See accompanying drawing 2, it is top view.In order to better control the motion of iron ball 5, the shape of cross section of the first track is circular arc.In like manner can obtain, the shape of cross section of the second track 2, the 3rd track 3 is also circular arc.
