Description
Technical field
The utility model relates to physical teaching aid field, especially a kind of Novel physical flat parabolic experimental apparatus for demonstrating.
Background technology
Level throw motion is an important content of courses in physics teaching in secondary school, how directly perceived, vividly carry out experimental demonstration to help that student understands be a difficult point in physics teaching, on textbook with stroboscopic photograph obtain photo be afterwards secondhand, instead of with the naked eye observe directly, student not easily understands, and existing experimental apparatus structure is simple, visual effect is poor, error is large, and bead initial velocity is wayward, and teaching efficiency is undesirable.Level throw motion is the resultant motion of the freely falling body on the linear uniform motion of horizontal direction and vertical direction, and this point is difficult to embody in original experiment.In order to address this problem, need to start with from improvement demonstration instrument, student can in person be observed by experiment and record data, and carries out the calculating of test data, the understanding of student to level throw motion principle and formula is deepened, improves the teaching efficiency of experiment of horizontal projectile motion demonstration.
Utility model content
The purpose of this utility model provides a kind of Novel physical flat parabolic experimental apparatus for demonstrating to overcome above-mentioned technical disadvantages.
The technical scheme that the utility model technical solution problem adopts is: a kind of Novel physical flat parabolic experimental apparatus for demonstrating, comprise base, guide rod, ball receiving groove, guide rail, push-rod electric machine, plummet, described base is provided with 4 leveling bolts, base is provided with 2 guide rods vertical with base, guide rod is fixed with ball receiving groove, and the guide rod upper end in left side is provided with the guide rail vertical with guide rod, and guide rail is placed with steel ball, guide rail left end is provided with push-rod electric machine, is provided with fixed bar between rail end and guide rod.Ball receiving groove can prevent steel ball from jumping out, convenient experiment, and places printing paper paper tape in experiment time slot, can show the drop point of steel ball clearly, be convenient to recording level coordinate and carry out data calculating.
Described push-rod electric machine is provided with wire, and wire is connected with controller, and be provided with the vertical rod parallel with guide rod in the middle part of fixed bar, fixed bar is provided with vertical line, and vertical line end is provided with plummet.By controller can fine adjustment push-rod electric machine promote steel ball motion initial velocity, reduce experimental error.Be provided with vertical rod to compare with vertical line, better carry out instrument location and regulate.
Described guide rod and ball receiving groove all indicate scale, and ball receiving groove two ends are provided with sliding sleeve and are enclosed within guide rod, and sliding sleeve is provided with set bolt.Be provided with scale and better can record flat coordinate x and y numerical value that to throw on curve any, be convenient to carry out data calculating.
The beneficial effect that the utility model has is: the utility model reasonable in design, can conditioning instrumentation level easily, steel ball initial velocity can control, decrease experimental error, can visual pattern carry out flat parabolic experimental demonstration, and carry out data calculating, substantially increase the teaching efficiency of experiment of horizontal projectile motion demonstration.
