Embodiment one
See accompanying drawing 1, it is structural representation of the present utility model.The synthesis Sum decomposition demonstrator of motion, comprise base 3, the vertical panel 4 be fixedly connected with base 3, it is characterized in that: vertical panel 4 is provided with a fixed pulley 6, this fixed pulley 6 rotating shaft is perpendicular to panel 4 place plane, this fixed pulley 6 rotational plane is parallel to panel 4 place plane, a connecting strand be made up of flexible material 7 is through fixed pulley 6, and connecting strand 7 one end connects the first weight 1, the other end connects the second weight 2, first weight 1 dangles, second weight 2 is held on horizontal rail 5, horizontal rail 5 is fixedly connected with panel 4, and horizontal rail 5 place plane orthogonal is in panel 4 place plane, and connecting strand 7 place plane and fixed pulley 6 rotational plane are same planes.
In order to better reflect annexation, please see accompanying drawing 2, accompanying drawing 2 is side views.Accompanying drawing 2 has showed these technical characteristics: base 3, the vertical panel 4 be fixedly connected with base 3, vertical panel 4 is provided with a fixed pulley 6, this fixed pulley 6 rotating shaft is perpendicular to panel 4 place plane, this fixed pulley 6 rotational plane is parallel to panel 4 place plane, second weight 2 is held on horizontal rail 5, and horizontal rail 5 is fixedly connected with panel 4, and horizontal rail 5 place plane orthogonal is in panel 4 place plane.
Connecting strand 7 can be made with fine rule.
Using method: the second weight 2 is moved along horizontal rail in horizontal rail 5, measures the speed of the second weight 2, and measures the speed of the first weight 1 simultaneously, just can know the length velocity relation of the first weight 1 and the second weight 2.Various equivalent modifications should be known, and the first weight 1 is different with the velocity magnitude of the second weight 2.After measuring speed, the speed can measured with the knowledge research of the synthesis Sum decomposition of motion.
Measuring speed belongs to prior art.Such as speed pickup, is also motion sensor.
In order to the synthesis Sum decomposition of simpler study movement, the utility model can also like this:
Embodiment two
For the teaching aid of the synthesis Sum decomposition that moves, comprise base 3, the vertical panel 4 be fixedly connected with base 3, it is characterized in that: vertical panel 4 is provided with a fixed pulley 6, this fixed pulley 6 rotating shaft is perpendicular to panel 4 place plane, this fixed pulley 6 rotational plane is parallel to panel 4 place plane, a connecting strand be made up of flexible material 7 is through fixed pulley 6, and connecting strand 7 one end connects the first weight 1, the other end connects the second weight 2, first weight 1 dangles, second weight 2 is held on horizontal rail 5, horizontal rail 5 is fixedly connected with panel 4, and horizontal rail 5 place plane orthogonal is in panel 4 place plane, and: panel 4 surface is provided with the first scale 8 for measuring the first weight 1 displacement, horizontal rail 5 is provided with the second scale 9 for measuring the second weight 2 displacement, and connecting strand 7 place plane and fixed pulley 6 rotational plane are same planes.
Using method: move the second weight 2 along horizontal rail 5, often move once, the distance of the second weight 2 movement is just measured according to the second scale 9, simultaneously, the distance of the first weight 1 movement is measured by means of the first scale 8, because the time is identical, so, the distance of movement reflects the average velocity of the first weight 1 and the second weight 2, continuous moving second weight 2, optimal way is each mobile identical distance, according to the change of each difference in height of the first weight 1, just can know that the acceleration of the first weight is in change.Utilize data can probe into the synthesis Sum decomposition of motion.
The utility model structure is simple, benefits to student's inquiry activity.
