Problems solved by technology

[0002] In high school physics teaching, "force synthesis" is a very important lesson, it is the starting point of vector teaching, and it is also the focus and difficulty of high school physics teaching, while the experiment used in traditional physics teaching is to use wooden boards, thumbtacks, white paper , rubber band, and two spring dynamometers. In the experiment, the rubber band is easy to age and deform after being stretched several times, resulting in large errors, and the experiment can only be carried out on the desktop, and the teacher cannot demonstrate it intuitively. In the experiment, in the process of drawing pictures, the operability of the experiment is relatively high for one person to complete the experiment. It is necessary to punctuate and mark the stretching direction while pulling the spring dynamometer.

Embodiment Construction

[0009] The present invention proposes a synthetic demonstrator for dynamically suspended self-weight force, which can draw a synthesizing schematic diagram of force conveniently and quickly, and demonstrate experiments more intuitively.

[0010] The structure diagram of the present invention is as figure 1 As shown, the instrument is mainly composed of screw 1, No. 1 dynamometer 2, No. 1 pulley 3, No. 1 string 4, converging force angler 5, vertical rod 6, object 7, No. 3 pulley 8, and an arched door opening. 9. Support frame 10, leveling bolt 11, sign cone 12, heavy hammer with line 13, empty slot 14, No. 4 pulley 15, panel 16, No. 2 string 17, semicircular groove rail 18, No. 2 pulley 19 , No. 2 dynamometer 20, wherein the panel 16 has a hollowed arched door opening 9, a semi-circular groove track 18 is arranged above the arched door opening 9, and an empty slot 14 is arranged at the lower right corner of the panel 16. The empty slot 14 is fixed with a line weight 13, and th...

Abstract

The invention provides a composition demonstration instrument for dynamically hanging dead weight type force. The instrument mainly comprises a dynamometer, an arched door opening, a pulley, a string,a force converging protractor, an object block, a panel, a semicircular grooved rail and the like, wherein the arched door opening, the semicircular grooved rail and the force converging protractor are arranged in the middle of the panel and can move freely, and the instrument is easy to operate, high in intuition, small in error, obvious in demonstration experiment effect and beneficial to understanding of students on physical knowledge.

Description

technical field [0001] The invention relates to a middle school physics teaching and experimenting instrument, in particular to a synthetic demonstration instrument for dynamically hanging self-weight force. Background technique [0002] In high school physics teaching, "force synthesis" is a very important lesson, it is the starting point of vector teaching, and it is also the focus and difficulty of high school physics teaching, while the experiment used in traditional physics teaching is to use wooden boards, thumbtacks, white paper, etc. , rubber band, and two spring dynamometers. In the experiment, the rubber band is easy to age and deform after being stretched several times, resulting in large errors, and the experiment can only be carried out on the desktop, and the teacher cannot demonstrate it intuitively. In the experiment, in the process of drawing, the operability of the experiment is relatively high for one person to complete the experiment. It is necessary to p...
