Abstract
The utility model belongs to the field of physics teaching aid, in particular to a high school physics teaching aid capable of simulating interaction relation among molecular forces. The high school physics teaching aid is characterized in that a strip-shaped locating slot is formed at the upper end of a base, two ring-shaped magnets matched with the locating slot are arranged in the locating slot, a support is fixed at the lower end of the base between the two ring-shaped magnets, and the support supports a U-shaped magnet through a rotation device. The utility model has the advantages of simple structure, convenience in operation, and capability of improving students' comprehension ability and study interests.
Description
Technical field: the utility model belongs to physics teaching apparatus field, but is specifically related to the physics teaching in secondary school apparatus of interaction relationship between a kind of model molecule power.
Background technology: the many notions in the junior physics teaching material, rule, law are all introduced by experiment, are derived and verify, especially in mechanics teaching, interaction relationship is important and one of the content of beyonding one's depth between the molecular force, do not have teaching aid targetedly at present again, adopt mostly according to the mode of originally explaining and publicising, more abstract hard to understand, the student lacks the chance of starting to test again, Faculty and Students are difficult to produce interactive, thereby bring certain difficulty to teaching, cause the student not have learning interest.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, and is easy to operate, can improve the physics teaching in secondary school apparatus of student's understandability and learning interest.
The technical solution of the utility model is: a kind of physics teaching in secondary school apparatus, it is characterized in that: be provided with the strip locating slot in the base upper end, be provided with two ring-shaped magnets that are mated in the locating slot, base lower end built-in mounting between two ring-shaped magnets, bearing supports " U " shape magnet by whirligig.
Wherein, described whirligig is made up of the platform that revolves that matches with bearing, revolves in the pickup groove of platform upper surface to establish " U " shape magnet, revolves to establish holding screw between platform and the bearing the two is fixed in together.
Owing to adopt technique scheme, pass through revolving-turret, can change the direction of " U " shape magnet, thereby can observe two ring-shaped magnet motion conditions, when the two is mobile in opposite directions, represent distance between two ring-shaped magnets greater than intermolecular distance, promptly the two attracts each other, represent that intermolecular gravitation greater than repulsion, demonstrates gravitation between the molecule; Otherwise, opposing when mobile when the two, represent distance between two ring-shaped magnets less than intermolecular distance, promptly the two repels mutually, represents that intermolecular gravitation less than repulsion, demonstrates repulsion between the molecule; Can show abstract theory by teaching aid, be convenient to the student and understand, thereby have simple in structurely, easy to operate, can improve the advantage of student's understandability and learning interest.
Description of drawings: come the technical solution of the utility model is described further below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
Embodiment: with reference to the accompanying drawings, a kind of physics teaching in secondary school apparatus, be provided with strip locating slot 2 in base 1 upper end, be provided with two ring-shaped magnets 3,4 that are mated in the locating slot 2, base 1 lower end built-in mounting 5 between two ring-shaped magnets, bearing 5 supports " U " shape magnet 6 by whirligig; Described whirligig is made up of the platform 8 that revolves that matches with bearing 5, revolves in the pickup groove of platform 8 upper surfaces to establish " U " shape magnet 6, revolves to establish holding screw 7 between platform 8 and the bearing 5 the two is fixed in together.
