Description
Technical field
This utility model belongs to physical teaching aid field, is specifically related to a kind of Newton's third law education demonstrator.
Background technology
The content of Newton's third law is mainly: active force and counteracting force between two objects are always equal in magnitude, in opposite direction, on same straight line. Newton's third law is one of key content of Middle School Physics, although law is full of in our daily life, but student is very unilateral again to the understanding of law, and understanding is also insufficient. As equal in magnitude in active force and counteracting force, the bad acceptance of student, largely govern the understanding of student.
Summary of the invention
This utility model, in order to solve problem mentioned above, makes up the deficiency of conventional art, it is provided that a kind of simple in construction, the Newton's third law education demonstrator that easy to operate, phenomenon is distinct.
This utility model is achieved by the following technical solution:
A kind of Newton's third law education demonstrator, including support rod and collision body, it is characterised in that: support rod is long thin straight bar structure, and its two ends are respectively arranged with an elastic clip; Described collision body includes Magnet set, Magnet, funnel and curve; Magnet set is circular card nested structure, and its top is provided with link; Arranging round-meshed circular plate structure centered by Magnet, Magnet noose is internal at Magnet set; Funnel noose is in the center hole of Magnet; Curve concave side buckles in the opposition side spilling tremie tube.
Described magnetic blow out centre circular hole is the ramp type structure coincideing with funnel inclined-plane.
Described tremie tube is marked with graduation mark.
Described curve adopts rubber to make.
The beneficial effects of the utility model are, simple in construction is easy to operate, it is possible to the visual in image relation representing active force and counteracting force size, direction, help student to understand, and contribute to the quick raising of student, are suitable to wide popularization and application.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that this collision body structure assembles figure.
In figure, 1 support rod, 2 elastic clips, 3 collision bodies, 4 Magnet sets, 5 Magnet, 6 funnels, 7 curve.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.
Newton's third law education demonstrator of the present utility model, including support rod 1 and collision body 3, it is characterised in that: support rod 1 is long thin straight bar structure, and its two ends are respectively arranged with an elastic clip 2; Described collision body 3 includes Magnet set 4, Magnet 5, funnel 5 and curve 7; Magnet set 4 is circular card nested structure, and its top is provided with link; Arranging round-meshed circular plate structure centered by Magnet 5, Magnet 5 noose overlaps inside 4 at Magnet; Funnel 6 noose is in the center hole of Magnet 5; Curve 7 concave side buckles in the opposition side spilling tremie tube; Described Magnet 5 center hole is the ramp type structure coincideing with funnel inclined-plane; Described tremie tube is marked with graduation mark; Described curve 7 adopts rubber to make.
During test, the tremie tube same position of collision body 3 injects red ink to the left and right, pressing elastic clip 2, the collision body 3 that release is blocked by elastic clip 2, the rubber curve 7 of collision body 3 attracts collision, rubber curve 7 internal gas pressurized under the effect of magnet suction, and red ink post is moved, from the relation flowing to observable active force and counteracting force direction of water column, examine the relation of active force and counteracting force size from the appreciable lengths of water column.
