Abstract
The present invention provides a kind of pipeline that tests the speed of teaching, it is characterized in that, including pipeline, velometer, park part and chassis, the pipeline is small one and large one circular straighttube road, pipeline upper end open, and lower end is connected with chassis, the velometer is located at close to duct bottom with part is parked, velometer is located on the outside of pipeline, parks part and is located at insides of pipes, velometer, which is located at, to be parked above part.The present invention can simulate Galilean leaning tower falling body experiment, increase the vividness of teaching, teach through lively activities.
Description
Technical field
The invention belongs to teaching equipment field, more particularly, to a kind of pipeline that tests the speed of teaching.
Background technology
Galilean leaning tower experiment is a classical physics story, while involved acceleration of gravity is junior physicses book
A upper important section, if because sounding uninteresting without demonstration object, student, being not easy to grasp its knowledge point in teacher's hand,
Learning knowledge is only limitted to theory, is only limitted on books.
The content of the invention
The problem to be solved in the present invention is to provide a kind of pipeline that tests the speed of teaching, and it is real can to simulate Galilean leaning tower
Test, increase the vividness of teaching.
In order to solve the above technical problems, the present invention provides a kind of pipeline that tests the speed of teaching, including pipeline, velometer, stop
Part and chassis are put, the pipeline is small one and large one circular straighttube road, and pipeline upper end open, lower end is connected with chassis, described
Velometer is located at close to duct bottom with part is parked, and velometer is located on the outside of pipeline, parks part and is located at insides of pipes, tests the speed
Device, which is located at, to be parked above part.
Further, the velometer is infrared ray or laser velocimeter device.
Further, the material of the pipeline is transparent plastic.
Further, described park has cushion on part.
The present invention has the advantages and positive effects of：
1st, it is easy to make, simple to operate, economically feasible；
2nd, entertaining is full, teaches through lively activities, and is easy to student's profound lesson physical knowledge；
3rd, it is vivid, motivate students' interest in learning.

Embodiment
Here is that the present invention is further described with reference to accompanying drawing：
The present invention provides a kind of pipeline that tests the speed of teaching, including pipeline 1, velometer 2, parks part 3 and chassis 4, the pipe
Road 1 is small one and large one circular straighttube road, and big circular straight pipeline radius is 20CM, and small circular straight pipeline radius is 8CM, large and small
The height of pipeline is 2M, the upper end open of pipeline 1, and lower end is connected with chassis 4, the velometer 2 and parks part 3 and is located at close to pipe
The bottom of road 1, velometer 2 are located at the outside of pipeline 1, park part 3 and are located at the inner side of pipeline 1, velometer 2, which is located at, parks the top of part 3.
Velometer principle：The velometer 2 uses infrared ray velometer, and it is that testee is carried out twice that infrared ray, which tests the speed,
There is the infrared distance measuring of specified time interval, obtain the displacement of the testee within a period, it is tested so as to obtain this
The translational speed of object.
In use, first opening infrared ray velometer 2, two objects for needing to test then are found, the test articles are
Circular optimal, quality gap is larger, test articles then is individually placed into the upper end open of pipeline 1, while hand is decontroled into observation simultaneously
Record test articles fall parking the time of part 3, and further read the numerical value of the measurement of infrared ray velometer 2 respectively, so as to
Understand the physical principle and process entirely tested.
One embodiment of the present of invention is described in detail above, but the content is only the preferable implementation of the present invention
Example, it is impossible to be considered as the practical range for limiting the present invention.All equivalent changes made according to the present patent application scope and improvement
Deng, all should still belong to the present invention patent covering scope within.
