Abstract
The utility model discloses an inertia demonstration device for physics teaching, comprising a body and wheels disposed below the body. The body is provided with a demonstration case, and a small ball is disposed on the demonstration case. The small ball is provided with an elastic rope fixedly connected to the demonstration case. The upper surface of the demonstration case is provided with a sliding groove for controlling the movement track of the small ball. The small ball is disposed in the sliding groove, and one wheel is provided with a motor for driving a connection shaft disposed between two wheels to move. The bottom part of the body is provided with a wheel rail for controlling the movement track of the wheels, and the front end of the wheel track is provided with a baffle plate. The inertia demonstration device for physics teaching is advantageous in that the structure is simple; the inertial of the object-moving state can be demonstrated, and demonstration effect can be ensured; the movement rack of the body and the small ball can be controlled; safety for students can be guaranteed, and teaching quality can be improved.
Description
Technical field
The utility model relates to physical teaching aid technical field, is specifically related to a kind of physics teaching inertia demonstrator.
Background technology
At present, student, in Learning from Nature section class hour, is generally provided with laboratory, can help by experiment student to accelerate to grasp various principles, law, particularly chemistry and the course such as physics, and laboratory is absolutely necessary.In existing physics educational apparatus, can only demonstrate the fundamental property of object inertia when static, and inertia performance can not demonstrate object of which movement time, during the law of inertia in Students ' Learning physics, can only rely on teacher's explanation of drawing on blackboard, not directly perceived, affect student's understanding, thereby reduced quality of instruction.In addition, the apparatus of the demonstration law of inertia does not have the movement locus of regulation, and easily landing damages, and cannot guarantee student's safety, has increased instruction cost.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, provide a kind of simple in structure, can demonstrate the inertia of object moving state, can guarantee demonstration effect, can control the movement locus of car body and bead, guarantee student's safety, the physics teaching inertia demonstrator that can improve the quality of teaching.
Its technical scheme is: physics teaching inertia demonstrator, comprise car body and the wheel that is arranged on car body below, described car body is provided with demonstration box, the top of described demonstration box is provided with bead, described bead is provided with the elastic threads being fixedly connected with demonstration box, the upper surface of described demonstration box is provided with for controlling the sliding tray of bead movement locus, described bead is positioned at sliding tray, on a wheel, be provided with for driving the motor of two coupling shaft motions between wheel, the bottom of described car body is provided with for controlling the wheel track of wheel trace, the front end of described wheel track is provided with baffle plate.
One side of described demonstration box is provided with chamber door.
The place ahead of described car body is provided with hook, and described hook is provided with stay cord.
Described wheel track is plug in construction.
The utility model compared with prior art, has the following advantages: simple in structure, can demonstrate the inertia of object moving state, and can guarantee demonstration effect, can control the movement locus of car body and bead, guarantee student's safety, can improve the quality of teaching.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, physics teaching inertia demonstrator, comprise that car body and 1 is arranged on the wheel 2 of car body 1 below, described car body 1 is provided with demonstration box 3, the top of described demonstration box 3 is provided with bead 4, described bead 4 is provided with the elastic threads 5 being fixedly connected with demonstration box 3, the upper surface of described demonstration box 3 is provided with for controlling the sliding tray 6 of bead 4 movement locus, described bead 4 is positioned at sliding tray 6, on a wheel 2, be provided with for driving the motor 8 of two coupling shaft 7 motions between wheel, the bottom of described car body 1 is provided with for controlling the wheel track 9 of wheel 2 movement locus, the front end of described wheel track 9 is provided with baffle plate 10.
One side of described demonstration box 3 is provided with chamber door 11.By demonstration box 3, can deposit various teaching aids, facilitate teacher's use of imparting knowledge to students.
The place ahead of described car body 1 is provided with hook 12, and described hook 12 is provided with stay cord 13.By stay cord 13, facilitate teacher manually to make car body 1 do at the uniform velocity or variable motion, the convenient demonstration law of inertia.
Described wheel track 9 is plug in construction.Can reduce floor area like this, conveniently deposit.
When car body 1 is static, bead is positioned at transfixion on demonstration box 3, during manual operation, when pulling fast stay cord 13 and forwards pull car body 1, bead 4 rolls round about in sliding tray 6, and when at the uniform velocity pulling car body 1, bead 4 is motionless, illustrates that object has the character that keeps stationary state, when car body 1 runs into barrier as baffle plate 10 cut, can see that bead 4 rolls to the direction of motion, illustrates that object has the straight-line character that remains a constant speed.By elastic threads 5, can prevent that bead 4 tumbles and accidentally injures student from demonstration box 3 when demonstrating, good demonstration effect, easy to use, can alleviate teacher's burden.By motor 8, can be with motor vehicles bodies 1 to do at the uniform velocity or variable motion, the convenient demonstration law of inertia, can alleviate teacher's burden, wherein motor 8 is connected with accumulator by controller, and the switch of opening during use on controller can be controlled motor 8 band motor car wheels 2 rotations.During car body 1 motion, wheel 2, in the interior movement of wheel track 9, can not only prevent the damage of dropping like this, and can prevent that car body 1 and bead 4 from going out because of inertia, and injures student, can guarantee student's safety.
The utility model is simple in structure, can demonstrate the inertia of object moving state, can guarantee demonstration effect, can control the movement locus of car body and bead, guarantees student's safety, can improve the quality of teaching.
