Description
Technical field
The utility model relates to tutor auxiliary platform teaching aid field, specifically a kind of physics teaching demonstration device.
Background technology
In junior middle school physics teaching, resolution of force is as an important basic theoretical knowledge point, traditional form of teaching is that the theory explaination that teacher is simple coordinates certain writing on the blackboard to carry out, lateral stressed situation and longitudinal stress situation is calculated by mathematical operation, and for diverse location, the example of different angles, needs recalculate, so, not only increase the burden of teacher, need frequently to carry out writing on the blackboard, and easily make student produce boredom, knowwhy can not be understood intuitively, have impact on the learning efficiency of student, some simple experimental devices can adopt force snesor can carry out the experimental demonstration of different angles in good time, but such device does not have leveling unit usually, experimental provision carries out experiment under the state that can not determine horizontal positioned can cause sizable error, can not mate with the mathematical computations of theory, have impact on student to understand.
Utility model content
In order to solve the problem, provide a kind of physics teaching demonstration device of improvement.
The technical solution of the utility model is: a kind of physics teaching demonstration device, this device mainly comprises experiment table (1), inclinometer (2), slideway (3), levelling pendant (13) and support (4), described slideway (3) is connected on experiment table (1) by articulated joint (6), described experiment table (1) is also provided with longitudinal stress plate (7), weight block (5) is placed on slideway (3) and longitudinal stress plate (7), its middle slideway (3) and longitudinal stress plate (7) are equipped with force snesor, described experiment table (1) is provided with transverse force display screen (11) and longitudinal force display screen (10), described inclinometer (2) is provided with scale mark (16) and positioning runner (9), described slideway (3) is provided with locating piece (8), slideway (3) can be fixed along positioning runner (9) by described locating piece (8), described experiment table (1) below connection bracket (4), support (4) is by bolt (15) auxiliary connection support (14), the end of assistant support (14) is provided with rubber suction cups (17), the below of described experiment table (1) is provided with levelling pendant (13) and scale (12).
The utility model has following beneficial effect: teacher adjusts pole by levelling pendant and scale thus ensures that experiment table is horizontal, simultaneously show the pressure of weight block on horizontal and vertical in real time by pressure transducer, make the computing method that student gets information about resolution of force and makes a concerted effort, and can be matched with the empirical value of reality by the empirical value of theoretical calculation method gained, while improve students ' interest of study, alleviate the burden of giving lessons of teacher, substantially increase efficiency of giving lessons, this experimental provision structural design is simple, intuitively, easy to operate, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
