Abstract

The invention discloses a vector composition and resolution analyzer. The analyzer is an instrument which can visually and intuitively help students study and understand composition and resolution of a vector (force), display the magnitude of a resultant vector and the magnitude of a vector component and have regular direction change. The analyzer is realized by punching and trenching on a wood strip and fixing or limiting with screws. The analyzer can be used as a teaching aid of a teacher for teaching as well as a learning aid of a student for learning.

Description

Synthetic and the decomposition analysis instrument of vector

Affiliated technical field:

The present invention is that a kind of energy helps middle school student to learn to understand the synthetic of vector (power) and decompose visual in imagely, the instrument that shows resultant vector (power) and the big or small direction Changing Pattern of resolute (power) especially can strengthen present Chinese middle school and give birth to the generally manipulative ability of shortcoming.

Back of the body border technology:

Manipulative ability (one of experiment innovation exploring ability) is China middle school student's a weakness always, and in order to change this present situation, country has put into effect multiple countermeasure and planning, and particularly the new curricular reform of now implementing is expected to change as early as possible this situation.This instrument is just in order to cooperate new curricular reform, allow a high new life adapt to the study of senior middle school as early as possible, improve students'ability for practice, deeply understand the synthetic of vector (power) and decompose, grasp some effort of doing with component size direction Changing Pattern with joint efforts, be intended to cast a brick to attract jade, hope more colleague pool our ideas and make concerted efforts, make the contribution of oneself for the smooth implementation of new curricular reform.

Summary of the invention:

In order to make the student learn the synthetic of abstract relatively vector (power) and decompose more visual in imagely, improve students'ability for practice, and designed this instrument.Make a concerted effort with the variation relation of corner dimension when this instrument can not only be demonstrated and analyze component and determine, also can analyze the Changing Pattern of two component and angle when making a concerted effort to determine.

The technical solution adopted in the present invention is: punching and kerve on batten by the size and the direction of hole (and screw) fixed vector (power), show size and the direction situation of change and the rule of vector (power) by the slip of hole in groove.

The invention has the beneficial effects as follows: instrumentation is simple, and manufacturing materials is abundant, shows that vector changes image, lively, directly perceived, can effectively cultivate the ability of student's hand brain and usefulness, can motivate students' interest in learning again.

Description of drawings:

The present invention is further described below in conjunction with accompanying drawing

Fig. 1 is all component diagram of instrument of the present invention

Fig. 2 be demonstration analyze resolute (power) fixedly resultant vector (power) with variable angle the change operation structural drawing

Fig. 3 be demonstration analyze resultant vector (power) fixedly resolute (power) with variable angle the change operation structural drawing

Fig. 4 is that demonstration analysis resultant vector (power) direction determines that one of them resolute (power) is the minimum operation structural drawing when vertical with another resolute (power)

Embodiment:

Each parts among Fig. 1 can be analyzed demonstration by Fig. 2, Fig. 3, installation shown in Figure 4 after regulating.

Claims

1. a vector synthesizes and the decomposition analysis instrument, punching and kerve on strip material, fix or limit by screw, it is characterized in that: use synthetic parallelogram (triangle) rule of vector, when the angle of expression direction vector changes, the length along path bob of expression vector size is given birth to corresponding variation, and vice versa.

2. the synthetic and decomposition analysis instrument according to the described vector of claim is characterized in that: can make performance analysis to size, the direction relations of resultant vector and resolute.
