Description
Technical field
The utility model relates to a kind of experimental provision verifying the law of conservation of momentum, belongs to education experiment field.
Background technology
In the experiment of the checking law of conservation of momentum, traditional experiment method is that the motion state after research two beads collide changes the calculating carrying out momentum, and then the checking law of conservation of momentum, then the collision moment of bead, the data such as fall time and drop point site all need student to detect by an unaided eye and record, therefore be difficult to obtain experimental data accurately, flashy error may cause the failure of whole experiment, take great energy effort and also can not get expected result, affect the efficiency of student experimenting class.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, compact conformation, the experimental provision of the checking law of conservation of momentum of functional module energy organic assembling.
The technical scheme in the invention for solving the above technical problem is: a kind ofly verify that the experimental provision of the law of conservation of momentum comprises roller track, pressure sensing bar and controller, roller track comprises inclined plane and horizontal rail, the lower surface of horizontal rail is provided with level governor, the end of horizontal rail is provided with voltage sensitive sensor, pressure sensing bar and voltage sensitive sensor are all electrically connected with controller, and controller is provided with timer and display screen.
As preferably, the utility model also comprises incident bead and is hit bead, incident bead and to be hit bead be all stainless steel, and incident bead is 500g, and being hit bead is 300g.
As preferably, roller track is provided with groove, and groove is circular groove, is convenient to the rolling of bead.
As preferably, between inclined plane and horizontal rail, be provided with hinge, the angle regulating inclined plane to tilt by hinge, and then change experiment parameter.
As preferably, the utility model also comprises printer, and printer is electrically connected with controller, is convenient to student and prints experiment drawing and data, complete laboratory report.
As preferably, pressure sensing bar and roller track are positioned at same plane, guarantee that bead can be fallen on pressure sensing bar after departing from roller track, are convenient to drawing of experimental data.
The utility model compared with prior art, have the following advantages and effect: the utility model compact conformation, novelty, voltage sensitive sensor and pressure sensing bar is adopted to respond to fall time and the drop point site of bead, make data more accurate, student can be made to obtain experimental result more accurately, improve the efficiency of laboratory.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Label declaration: 1-roller track, 2-pressure sensing bar, 3-controller, 4-level governor, 5-voltage sensitive sensor, 6-timer, 7-display screen, the incident bead of 8-, 9-is hit bead, 10-printer.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
As shown in Figure 1, the experimental provision of the checking law of conservation of momentum of the present embodiment comprises roller track 1, pressure sensing bar 2 and controller 3, roller track 1 comprises inclined plane and horizontal rail, the lower surface of horizontal rail is provided with level governor 4, the end of horizontal rail is provided with voltage sensitive sensor 5, and pressure sensing bar 2 and voltage sensitive sensor 5 are all electrically connected with controller 3, and controller 3 is provided with timer 6 and display screen 7.
The present embodiment also comprises incident bead 8 and is hit bead 9, incident bead 8 and to be hit bead 9 be all stainless steel, and incident bead 8 is 500g, is hit bead 9 for 300g.
Roller track 1 is provided with groove, and groove is circular groove, is convenient to the rolling of bead.
Be provided with hinge between inclined plane and horizontal rail, the angle regulating inclined plane to tilt by hinge, and then change experiment parameter.
The present embodiment also comprises printer 10, and printer 10 is electrically connected with controller 3, is convenient to student and prints experiment drawing and data, complete laboratory report.
Pressure sensing bar 2 and roller track 1 are positioned at same plane, guarantee that bead can be fallen on pressure sensing bar after departing from roller track, are convenient to drawing of experimental data.
Adopt said structure, during experiment, first be placed on the voltage sensitive sensor 5 of horizontal rail end by hitting bead 9, level governor 4 is regulated to be hit bead 9 static, then incident bead 8 is placed on the highest point of roller track 1, unclamp bead, incident bead 8 is allowed freely to tumble, when incident bead 8 clash into hit bead 9 after leave roller track 1 together and start level throw motion, voltage sensitive sensor 5 senses pressure change and information is passed to controller 3, controller 3 is opened timer 6 and is started timing, and when incident bead 8 and hit bead 9 drop on respectively on pressure sensing bar 2 time, pressure sensing bar 2 passes to controller 3 information, controller 3 stops timer 6 and calculates drop point site and the fall time of two beads, shown by display screen 7, student verifies the law of conservation of momentum by the data obtained, then student changes the angle of inclination of inclined plane to carry out many experiments by regulating hinge, further reduction experimental error.Student can also by printer 10 experiment drawing and data-printing out, be convenient to laboratory report.
Above content described in this instructions is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of the utility model instructions or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
