Abstract
The utility model relates to a magnetic suspension Newton's second law demonstration instrument, comprising a base, a sliding block, a guide rail and a timing device. The guide rail composed of a magnetic suspension slot and a magnetic suspension train capable of moving in the magnetic suspension slot is provided with a scale and provided with the timing device. The magnetic suspension train is installed on the side edge of the magnetic suspension slot in a parallel way, and the sliding block is arranged on the magnetic suspension train. By adopting the magnetic suspension slot and the magnetic suspension train matched with the magnetic suspension slot as the guide rail and placing the sliding block on the magnetic suspension train, the magnetic suspension Newton's second law demonstration instrument of the utility model has the advantages of small friction force and relatively high verification accuracy.
Description
(1) technical field
The utility model relates to a kind of magnetic levitation Newton second law demonstrator.
(2) background technology
Common, the Newton second law demonstrator adopts air track, and slide block moves on air track, by the data verification Newton second law that records.Also the shortcoming of Cun Zaiing is: 1, exist friction between air track and the slide block, checking has limitation, have only mass M when air cushion＞＞during the quality m of slide block, checking could be more accurate; 2, air cushion exists noise problem; 3, the daily maintenance inconvenience of instrument affects the security of experimental teaching.So the structure of Newton's law demonstrator needs further improvement.
(3) summary of the invention
In order to overcome the lower deficiency of precision that the Newton's law demonstrator is measured in the prior art, the utility model provides a kind of novel Newton's law demonstrator, the floating car of the magnetic that adopt the magnetcisuspension floating trough, matches with the magnetic floating trough is as guide rail, slide block is positioned on the floating car of magnetic, friction force is very little, and the precision of checking is higher.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of magnetic levitation Newton second law demonstrator, comprise pedestal, guide rail and time set, described guide rail is provided with scale, described time set is installed on the guide rail, described guide rail is made of magnetic floating trough, the floating car of the magnetic that can move in the magnetic floating trough, the floating car of described magnetic is installed on the side of described magnetic floating trough abreast, and described slide block is placed on the floating car of described magnetic.
Further, described time set comprise two photogate, the memory-type millisecond meter of time that is used to write down slide block between two photogate.
Further again, described magnetic floating trough is connected with pedestal is movable.
The beneficial effect of magnetic levitation Newton second law demonstrator described in the utility model mainly shows: 1, the magnetic levitation notion is applied in the mechanics demonstrator, substituting air cushion with magnetic levitation suspends, slide block is placed on the floating car of magnetic, and friction force is very little, and the precision of measurement is higher; 2, adopt magnetic levitation to substitute air cushion and suspend, do not have noise; 3, the fairly simple convenience of the daily maintenance of instrument can guarantee its measuring accuracy for a long time.
(4) description of drawings
Fig. 1 is the structural representation of magnetic levitation Newton second law demonstrator.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of magnetic levitation Newton second law demonstrator comprises pedestal 5, guide rail, and guide rail is made of magnetic floating trough 1, the floating car 4 of the magnetic that can move in magnetic floating trough 1, and the floating car 4 of magnetic is installed on the side of magnetic floating trough 1 abreast, and slide block is placed on the floating car 4 of magnetic.The side of magnetic floating trough 1 bottom is provided with scale 3, and time set comprises two photogate 2, be used to write down slide block 6, two photogate of memory-type millisecond meter in the time between two photogate is installed on the magnetic floating trough, and the distance between two photogate is according to preestablishing.Magnetic floating trough 1 and 5 movable connections of pedestal can be adjusted the inclination angle of magnetic floating trough 1.Scale 3 records two distances between the photogate, and memory-type millisecond meter 6 records the time of slide block by two photogate, and the test method of magnetic levitation Newton second law demonstrator described in the utility model and traditional method are identical.
Claims (3)
1, a kind of magnetic levitation Newton second law demonstrator, comprise pedestal, slide block, guide rail and time set, described guide rail is provided with scale, described time set is installed on the guide rail, it is characterized in that: described guide rail is made of magnetic floating trough, the floating car of the magnetic that can move in the magnetic floating trough, the floating car of described magnetic is installed on the side of described magnetic floating trough abreast, and described slide block is placed on the floating car of described magnetic.
2, magnetic levitation Newton second law demonstrator as claimed in claim 1 is characterized in that: described time set comprises two photogate, the memory-type millisecond meter of time that is used to write down slide block between two photogate.
