Abstract
The utility model provides a physics teaching experiment tool comprising support racks, electromagnets, student power sources, high voltage generating devices, photoelectric doors and a base seat, wherein the electromagnets are connected with the student power sources; the electromagnets, the photoelectric doors and the base seat are orderly arranged on the support rack in a from-top-to-bottom manner; the support racks also are provided with scales and copper wire nets, and the high voltage generating devices is installed at two left and right sides of the copper wire nets. The beneficial effects of the physics teaching experiment tool are that the physics teaching experiment tool is reasonable in design, and therefore experiment reliability and precision can be improved, students can understand thoroughly, and simple operation and convenience of use are realized.
Description
Technical field
The utility model belongs to physics teaching experiment field, especially relates to a kind of physics teaching experiment apparatus.
Background technology
In common physical test, " freely falling body " is important and basic problem, the experiment equipment of taking is all experiment with falling objects instrument, exists following defect at current experiment with falling objects instrument: experimental precision is not high enough, job insecurity, uses inconvenient; Common experiment with falling objects instrument can only be used for doing movement of falling object experiment, and is not very convenient will complete other experiments time; Experiment effect is not fine, can not make understanding that students is clear and thorough etc.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of physics teaching experiment apparatus, is especially applicable to the freely falling body on abundant deduction classroom.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of physics teaching experiment apparatus, comprise support, electromagnet, student power source, high pressure generator, photoelectricity door, base, described electromagnet is connected with described student power source, described electromagnet, described photoelectricity door, described base are arranged on described support successively from top to bottom, on described support, also comprise scale and copper mesh, described high pressure generator is added in described copper mesh the right and left.
Described photoelectricity door is movable fixture.
Described base is provided with corresponding contact, pilot lamp, and described contact is connected by wire with described pilot lamp.
Described support outside is provided with glass supporter.
Described electromagnet is that J2444 type, described student power source are that J1202 type, described high pressure generator are J1206 type.
The each assembly of described physics teaching experiment apparatus is 2 covers.
The beneficial effect of utility model: the pilot lamp on operation base lights, the freely falling body phenomenon of observing " two different iron balls of quality land simultaneously " that student can be macroscopical; Calculate falling speed and the fall time of bead with light electric switch, show intuitively the process and the principle of covering up acceleration of gravity of freely falling body; Can prove that by dotted timer the movement of falling object is that initial velocity is zero uniformly accelrated rectilinear motion, be conducive to improve Classroom instruction quality, this instrument is easy to use, thought is comprehensive, conveniently returns something for repairs.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model
In figure:
1, support 2, electromagnet 3, photoelectricity door 4, base 5, contact 6, pilot lamp
Embodiment
As shown in Figure 1, a kind of physics teaching experiment apparatus of the utility model, comprise support 1, electromagnet 2, student power source, high pressure generator, photoelectricity door 3, base 4, electromagnet 2 is connected with described student power source, electromagnet 2, photoelectricity door 3, base 4 are arranged on support 1 successively from top to bottom, on support 1, also comprise scale and copper mesh, described high pressure generator is added in described copper mesh the right and left.Photoelectricity door 3 is movable fixture.Base 4 is provided with corresponding contact 5, pilot lamp 6, and contact 5 is connected by wire with pilot lamp 6.Support 1 outside is provided with glass supporter.Electromagnet 2 is that J2444 type, described student power source are that J1202 type, described high pressure generator are J1206 type.The each assembly of described physics teaching experiment apparatus is 2 covers.
The course of work of this example: when use, connect high pressure generator switch, regulation voltage, after stable, open electro-magnet switch, open photoelectricity door switch, the Metal Ball of different quality freely falls, and student can observe the Metal Ball of different quality and land simultaneously, thereby understand the characteristics of motion of freely falling body, can make student launch the study of correlation computations by photoelectricity door switch; On support, place blank sheet of paper bar, the wire netting on Metal Ball meeting and support produces electric spark, thereby leaves stain on blank sheet of paper bar, and students can be carried out according to the stain on blank sheet of paper bar the study of correlation computations.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
