Problems solved by technology

Some schools use a force balance demonstrator to demonstrate, and they can only do scalar calculations related to force, and cannot intuitively read the angle between each force. Usually, only specific angles can be used to obtain accurate values. , such as 30°, 45°, 60°, etc., and can only draw rough graphics on the blackboard, and cannot directly read out the data of angle and length; the angle calculation process is complicated and not intuitive enough

Embodiment Construction

[0008] The invention provides a set of vector slide rules, including a main ruler and a subsidiary ruler, which can quickly and accurately measure the size and direction of a vector by organically combining a new experimental scheme with a traditional experimental method. During the whole experiment process, as long as the position of the slider is adjusted as needed, and it is connected with a tape, the size and direction of the vector can be read intuitively without complicated calculations.

[0009] The structural schematic diagram of the auxiliary ruler of the present invention is as figure 1 As shown, including ruler tail (1), circle center (2), ruler body (3), thin steel wire (4), short screw (5), slider (6), empty slot (7) and ruler head (8) . Among them, the end of the ruler (1) is a transparent disc, on the end of the ruler (1), the direction of the thin steel wire (4) is used as the zero mark line, and the angle scale of 0°~180° symmetrical up and down is engraved o...

Abstract

The invention relates to a vector slide rule set, and belongs to the technical field of teaching instruments. The slide rule set is mainly composed of a main rule and an auxiliary rule, and comprisesa rule head, a rule body, a rule tail, a thin steel wire, a short screw, a sliding block, a flexible rule box and the like. The vector size represented by the unit length can be specified according toactual needs; and not only force synthesis demonstration but also synthesis operation of vectors such as speed, displacement and the like can be carried out. The slide rule set can intuitively read out an included angle between the vectors and calculate out the size of a resultant vector without complicated calculation, also can be used as a ruler to measure the length, and is simple to operate and is intuitive and convenient.

Description

technical field [0001] The invention relates to a physics teaching instrument, in particular to a set of vector slide rules. Background technique [0002] Vector calculation is an important knowledge throughout high school physics, which includes the calculation of physical quantities such as displacement, velocity and force. At present, when explaining vector calculations in middle school physics classes, we can only draw abstract vector graphics on the blackboard, and use mathematical formulas to calculate the results. Some schools use a force balance demonstrator to demonstrate, and they can only do scalar calculations related to force, and cannot intuitively read the angle between each force. Usually, only specific angles can be used to obtain accurate values. , such as 30°, 45°, 60°, etc., and can only draw rough graphics on the blackboard, and cannot directly read out the data of angle and length; the angle calculation process is complicated and not intuitive enough. ...
