Description
Technical field
The utility model relates to a kind of demonstrator, specifically a kind of physical experiment demonstration device, for demonstrating the presentation tool of object horizontal cast movement track in physics, belongs to teaching aid field.
Background technology
In physics teaching, teacher's normal Binding experiment explanation level throw motion.Traditional horizontal cast movement demonstration instrument can only realize a level throw motion usually, or level throw motion adds vertical falling motion, or is that level throw motion adds water flat linear uniform motion, and three motions are separately or combine between two; In addition, tradition is flat throws instrument to put down the electromagnet thrown on track is fixing non-adjustable, is doomed steel ball invariant position, such that flat to throw steel ball horizontal initial rate non-adjustable, makes experimental demonstration effect comprehensive, affects quality of instruction.
Utility model content
Technical problem to be solved in the utility model, proposes a kind of horizontal cast movement demonstration instrument that comprehensively can reflect level throw motion exactly.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of horizontal cast movement demonstration instrument, comprise the horizontal base and demonstration board that are mutually vertically fixedly connected with, described horizontal base is provided with leveling serew and level meter, the first chute is fixed with above the side of described demonstration board, the horizontal rail part of described first chute is parallel with horizontal base, described first chute is fixed with the first electromagnet by adjustment bolt, described first chute horizontal segment end is also provided with optoelectronic switch, it is characterized in that: below described first chute, be also fixed with the second chute, described second chute fixes the second electromagnet by adjustment bolt, 3rd electromagnet is hung on demonstration board top by support, described demonstration board is also provided with switch, described electromagnet is provided with adjustment sheet, described 3rd electromagnet is provided with setting nut, setting nut and support screw are spirally connected.
Further, described base is that steel plate plastic-blasting forms.
Further, described demonstration board is provided with coordinate system, and the starting point coordinate axle of coordinate system aligns with the first chute horizontal segment end.
Further, described second chute horizontal segment slide rail length is not less than coordinate system length.
Compared with prior art, the beneficial effect that the utility model has is:
1. utilize electromagnet to be provided with adjustment sheet, regulate the first electromagnet equal to obtain identical horizontal initial rate to respective chute horizontal segment height with the second electromagnet, two steel balls are inhaled respectively on the first electromagnet and the second electromagnet, disconnect experiment switch again, when two steel balls leave respective chute, horizontal initial rate is identical, can see that two balls bump against, repeat twice experiment, phenomenon is the same, illustrates that level throw motion componental movement is in the horizontal direction linear uniform motion.
2. two steel balls are inhaled respectively on the first electromagnet and the 3rd electromagnet, open test power supply again, when the steel ball discharged by the first chute leaves chute end, trigger optoelectronic switch, make the 3rd electromagnet power-off, steel ball on it does the movement of falling object simultaneously, can see that two balls bump against at the volley, traversing carriage changes the position (left and right horizontal moves) of the 3rd electromagnet, repeat second trial, two balls still can bump against at the volley, illustrate that level throw motion object and freely falling body same height time used of falling is identical, namely the componental movement of level throw motion in the vertical direction is the movement of falling object.
3. a steel ball is inhaled on the second electromagnet, disconnect experiment switch, record steel ball pick-up point, 3rd electromagnet is moved to directly over pick-up point, three steel balls are inhaled on electromagnet respectively, open test power supply, can see that three steel balls bump against in pick-up point simultaneously, uses " tautochronism " that the rule of level throw motion is described further.
