Abstract
The utility model discloses an experiment teaching aid for a horizontal projectile motion. The experiment teaching aid comprises a base (1), a demonstration plate (2), a support frame (3) fixed on the base (1), and a horizontal projectile rail (4) installed on the support frame (3), wherein a traction mechanism (5) is arranged at the inlet side of the horizontal projectile rail (4); the traction mechanism (5) is connected with the support frame (3) via an elastic connection device (6); and impact rods (7) are arranged on the traction mechanism (5) and corresponding to the inlet of the horizontal projectile rail (4). With the adoption of the structure, the track of the horizontal projectile motion can be demonstrated, and the isochronism of the horizontal projectile motion and a horizontal uniform motion can also be demonstrated; and with the adoption of the traction mechanism, the different impact rods can accurately impact steel balls on different horizontal projectile rails during an experiment, so that a great experiment effect is obtained.
Description
Technical field
The utility model relates to a kind of physics facility, relates in particular to a kind of level throw motion experiment teaching aid.
Background technology
In senior middle school physics teaching, the level throw motion of object is an abstract process, make the student can understand level throw motion preferably in the different motion of level and vertical direction, need be by experiment teaching aid.
Summary of the invention
The utility model provides a kind of can demonstrate object level throw motion track, again can demonstrating level throw motion and the experiment teaching aid of horizontal uniform motion tautochronism.
The technical solution of the utility model is a kind of level throw motion experiment teaching aid, comprise base 1, demonstration board 2, be fixed on bracing frame 3 on the base 1, be installed in the flat throwing track 4 on the bracing frame 3, the entrance side of described flat throwing track 4 has draw-off mechanism 5, described draw-off mechanism 5 is connected with bracing frame 3 by elastic connecting device 6, and the corresponding flat entrance of throwing track 4 arranges drop bar 7 on described draw-off mechanism 5.
Horizontal ruler 9 and Vertical surveyors' staff 10 are arranged on the described demonstration board 2.
Level trough 11 is offered in the middle and lower part of described demonstration board 2, and interception net 12 is connected on the demonstration board 2 by level trough 11.
On the described draw-off mechanism 5 stretch hole 8 is set.
Described flat throwing track 4 has 3, and vertical distribution is on bracing frame 3.
Adopt this structure, not only can the demonstrating level throw motion track, and the tautochronism of energy demonstrating level throw motion and horizontal uniform motion, owing to adopted draw-off mechanism, when experiment, different drop bars can clash into the different flat steel balls of throwing on the tracks simultaneously accurately, makes experiment obtain good effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is structural representation of the present utility model.
Among the figure 1, base, 2, demonstration board, 3, bracing frame, 4, the flat track of throwing, 5, draw-off mechanism, 6, elastic connecting device, 7, drop bar, 8, stretch hole, 9, horizontal ruler, 10, Vertical surveyors' staff, 11, level trough, 12, the interception net, 13, steel ball.
Embodiment
As shown in Figure 1, the utility model comprises base 1, demonstration board 2, be fixed on bracing frame 3 on the base 1, be installed in the flat throwing track 4 on the bracing frame 3, the entrance side of described flat throwing track 4 has draw-off mechanism 5, described draw-off mechanism 5 is connected with bracing frame 3 by elastic connecting device 6, and the corresponding flat entrance of throwing track 4 arranges drop bar 7 on described draw-off mechanism 5.During experiment, pulling draw-off mechanism 5, under the effect of elastic connecting device 6, drop bar 7 bumps on the draw-off mechanism 5 are placed on the flat steel ball of throwing on the track 4 13, by demonstration board 2, observe the level throw motion track of steel ball 13.
At demonstration board 2 horizontal ruler 9 and Vertical surveyors' staff 10 are installed, are convenient to measure level and the vertical coordinate of object level throw motion track.
Offer level trough 11 in the middle and lower part of demonstration board 2, at level trough 11 interception net 12 is installed, interception net 12 can be in level trough adjusted horizontal coordinate.According to the size of traction force, regulate the horizontal level of interception net 12, arrive the effect of the flat paraboloid of interception.
Stretch hole 8 is set on the draw-off mechanism 5.Generally, be arranged on the center line of draw-off mechanism 5, namely evenly stressed, be convenient to tractive again.
The flat track 4 of throwing has 3, and vertical distribution is on bracing frame 3.Usually at the top, centre and bottom install.Middle flat throwing track 4 can VTOL (vertical take off and landing).Be convenient to flexible.
Owing to adopted draw-off mechanism, during experiment, difference is put down the steel balls of throwing on the tracks, is subjected to the bump of different drop bars simultaneously, has verified the tautochronism of level throw motion and horizontal uniform motion accurately, makes experiment effect more desirable.
Claims (5)
