Abstract
The utility model relates to a high school physics teaching tool, belong to culture and education articles, especially a teaching tool for demonstrating circular motion for supplement of existing high school physics teaching tools, being suitable for high school teachers and students, comprising a panel and a ball, a circular hole is disposed on center of the panel, the circular hole is installed with a cylinder disposed with a circular ring, the circular ring is tied with a thread, while the other end of the thread is tied with the ball; the panel is disposed with a hole for holding a candle. The panel can be installed with a piece of glass for reducing friction. The utility model has advantages as: simple structure, excellent operability, being capable of observing ball performing circular motion via eliminating all forces (friction force is about the same as zero) in horizontal direction, in order to enhance perceptual knowledge of students on Newton first law, being convenient for teachers to accomplish teaching task and enhance studying interest of students, also being helpful to develop student ability for analyzing and solving problems.
Description
Technical field
The utility model relates to a kind of physics teaching in secondary school apparatus, belongs to school supply and stationery, and the teaching aid that particularly a kind of demonstration moves in a circle is that suitable middle school student and teacher use in teaching to the replenishing of existing physics teaching in secondary school apparatus kind.
Background technology
Notion in the physical mechanics, law is more abstract hard to understand, and as Newton first law, all objects are not when being subjected to the external force effect, and rectilinear motion state or stationary state always remain a constant speed.Bring certain difficulty for like this teacher's teaching and student's study.
The utility model content
The utility model improves learning efficiency for the ease of teachers ' teaching and student, is intended to release a kind of academics and students of helping and imparts knowledge to students, increases the teaching aid to the perceptual knowledge of Newton first law.
The technical scheme that its technical matters that solves the utility model adopts is:
The teaching aid that a kind of demonstration moves in a circle comprises a panel and ball, and the face plate center place establishes a circular hole, and installation one is provided with the cylinder of annulus on the circular hole, is a fine rule on this annulus, and the other end of fine rule is a ball; Establish the hole that to adorn a candle on the panel.
Can lay a glass that is used for reducing friction on the described panel.
Described ball has ink, can stay movement locus during from panel or on glass slipping over.
The position in described hole is located at fine rule in the track that annulus moves in a circle, and after the candle in the hole lighted, can blow one was that one of annulus is the fine rule that ball moves in a circle around annulus.
Described panel can be the panel of plank, plastic plate or metal material.
Annulus and cylinder are for being rotatably connected, or fine rule is connected for the active line button with annulus.
The beneficial effect of the teaching aid that a kind of demonstration of the utility model moves in a circle is: simple in structure, can operate strong, by the institute that removes horizontal direction strong (friction force is approximately zero), observe the bead of making circular motion and will how to move, increase the perceptual knowledge of student to Newton first law; Promptly be convenient to the teacher and finish teaching task efficiently, improved the interest of student's study simultaneously again, be very helpful cultivating students ' analysis problem and problem-solving ability.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model;
The drawing reference numeral explanation:
1, panel 2, ball 3, cylinder 4, hole
5, glass 6, candle 7, fine rule
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, the utility model is to implement like this:
One panel 1 can be the panel of plank, plastic plate or metal material, and the center is established a circular hole; Circular hole is used for installing the cylinder 3 that is provided with annulus; Be a fine rule 7 on annulus, the other end of fine rule 7 is a ball 2, and has ink on the ball 2; Establish the hole 4 that can adorn a candle 6 on the panel 1, its position is located at fine rule 7 in the track that annulus moves in a circle.Lighted candle 6 allows ball 2 be with ink to make circular motion, can be that fine rule 7 tightly ties up on the annulus, and ring belt fine rule 7 and ball 2 rotate around cylinder 3; Also fine rule 7 usefulness active line link and connect annulus, and moving fine rule 7 of active line cingulum and ball 2 rotate around annulus.When fine rule 7 turns over the candle flame, just blow, ball 2 will move along a straight line, stay tangible motion path simultaneously, the confession academics and students observes the path of its motion, is subjected to the ball of centripetal force with more intuitive form cognition, remove the institute of horizontal direction strong after, ball 2 moves along a straight line.
Can lay a glass that is used for reducing friction 5 on the panel, add glass 5 back friction force and can reduce to minimum.
The above, it only is the preferred embodiment of the teaching aid that moves in a circle of a kind of demonstration of the utility model, be not that technical scope of the present utility model is imposed any restrictions, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model above any trickle modification, equivalent variations and modification that embodiment did.
