Description
Technical field
The utility model relates to a kind of horizon adjustable momentum conservation experiment instrument, is mainly used in large, special secondary school universities and colleges and physics experiments of high school teaching.
Background technology
At present, the checking momentum conservation experimental apparatus that senior middle school adopts utilizes the bead rolled down from oblique rail to go to collide and be still in bead horizontal rail to verify the law of conservation of momentum.This requirement of experiment is collided bead and is penetrated from horizontal rail by collision bead, and this just requires that instrument is level.And existing experimental apparatus does not have the function of adjustment level.If laboratory table is not level, bead is not aloft do level throw motion, can bring larger systematic error to experiment.
Summary of the invention
In order to overcome senior middle school's checking momentum conservation experimental apparatus, can not the shortcoming of level-off, be unlikely to again to make experimental apparatus too complicated, high cost, the utility model provides a kind of checking bead striking momentum conservation experimental apparatus, this checking momentum conservation experiment instrument energy level-off, thus the more accurate validation law of conservation of momentum, reduce systematic error, and simple, convenient.
The utility model comprises bead, track, T-shaped base, cord, taper weight, pyramidal projections, Level tune screw.A bead is placed on track inclined-plane, another bead is placed on the straight position of track, and track is fixed on T-shaped base, and T-shaped base three angles respectively fill a Level tune screw, cord system taper weight and is suspended on track upper end, and pyramidal projections is fixed on T-shaped base.Before doing the experiment of checking momentum conservation, first regulate the level of experimental apparatus.When straight position, track lower end is horizontal positioned, the taper weight of suspension is just in time above pyramidal projections.If track lower end is not level, regulate three Level tune screws of T-shaped base, by track level-off.The quality measuring two beads is respectively m
1and m
2.The horizontal shift s of level throw motion is after the bead measured on inclined-plane rolls across separately the horizontal position of track
1, then measure two beads do level throw motion horizontal shift s at track horizontal position collision rift
1 'and s
2 ', only need to calculate
equation is set up, and can verify momentum conservation.Because this experiment instrument has level(l)ing device, ensure that bead does level throw motion aloft, instead of inclined throw movements, decrease consequent systematic error.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is T-shaped base vertical views of the present utility model.
1. beads, 2. track in figure, 3. T-shaped base, 4. cord, 5. taper weight, 6. pyramidal projections, 7. Level tune screw.
Embodiment
A bead (1) is placed on track (2) inclined-plane, another bead (1) is placed on track (2) straight position, track (2) is fixed on T-shaped base (3), T-shaped base (3) three angles respectively fill a Level tune screw (7), cord (4) is that taper weight (5) is suspended on track (2) upper end, and pyramidal projections (6) is fixed on T-shaped base (3).Before doing the experiment of checking momentum conservation, first regulate the level of experimental apparatus.When straight position, track (2) lower end is horizontal positioned, the taper weight (5) of suspension is just in time in the top of pyramidal projections (6).If track (2) lower end is not level, regulate three Level tune screws of T-shaped base (3), by track (2) level-off.The quality measuring two beads is respectively m
1and m
2.Measure the horizontal shift s doing level throw motion after bead on inclined-plane (1) rolls across separately the horizontal position of track
1and s
2, then measure two beads (1) do level throw motion horizontal shift s at track (2) horizontal position collision rift
1 'and s
2 ', only need to calculate
equation is set up, and can verify momentum conservation.
Claims (1)
1. a horizon adjustable momentum conservation experimental apparatus, it is characterized in that: a bead is placed on track inclined-plane, another bead is placed on the straight position of track, track is fixed on T-shaped base, T-shaped base three angles respectively fill a Level tune screw, cord system taper weight and is suspended on track upper end, and pyramidal projections is fixed on T-shaped base.
