Image delineation instrument of fluorescence type single pendulum simple harmonic motion

Abstract

The invention discloses an image delineation instrument of fluorescence type single pendulum simple harmonic motion. The image delineation instrument comprises a long wooden plate, green fluorescence type light leaving cloth, a pendulum ball, a constant opening button, a constant closing button, a relay, a motor, a rotating wheel, a battery box, a wooden box, a vertical rod, a transverse bracket rod and a shaft, wherein the vertical rod is fixed on the long wooden plate thought screws; the pendulum ball is hung on the transverse bracket rod in a double suspension line mode; the wooden box is fixed at the upper end on the left side of the long wooden plate; the battery box is installed at the upper end on the rear side of the long wooden plate; the motor, the relay, the constant opening button and the rotating wheel are installed at the upper end on the front side of the long wooden plate; the shaft is installed on the rotating wheel; and the constant closing button is installed on the long wooden plate. When the image delineation instrument is used, the mass of the single pendulum ball is not changed in the swinging process, and the pendulum ball can be approximately taken as a mass point, so that a delineated image is an image generated from strict single pendulum simple harmonic motion; and moreover an existing device is improved so as to be more convenient and humanized when being used.

Description

technical field [0001] The invention relates to a physics teaching experiment instrument, in particular to an image tracing instrument for fluorescent simple pendulum simple harmonic motion. Background technique [0002] With the development of science and technology, the cultivation of students' scientific and technological innovation ability and the improvement of hands-on practical ability have been paid more and more attention by the society. Middle school education is also increasingly emphasizing students' active learning, focusing on creating a relaxed classroom atmosphere, no longer limited to boring words, and various teaching equipment are also used in the classroom. This puts higher demands on the original teaching equipment, which has the problems of bulkiness, high cost, and difficulty in on-site demonstration. The operation is simpler, the cost is lower, and it is easier to be widely used. [0003] In the lesson "Single Pendulum" in the chapter "Me...

AI Technical Summary

Problems solved by technology

As far as sand pendulums and water pendulums are concerned, since the center of mass of sand and water is constantly changing during the process of flowing out, they cannot be regarded as strict simple pendulums. In addition, there are problems that are inconvenient to display and cannot be recycled.

As for the single pendulum device modified by the electric spark timing timer, although the quality of the pendulum ball is guaranteed, it has many accessories that are not easy to carry and operate, and there is a risk of electric shock when it is powered on, and the safety factor is low, so it is not suitable as a classroom teaching aid.
