Description
Technical field
The technical program is related to teaching equipment technology field, especially a kind of horizontal projectile motion trajectory apparatus for demonstrating.
Background technology
For high school physics, the level throw motion of object is the emphasis in study, but since level throw motion is one
The concept of abstract then must be known by its movement locus and feature, due to current physics to study level throw motion in depth
Instructional mode is more single, can not be that student image shows level throw motion, therefore many students can not imagine the road of level throw motion
Line.For this problem, notification number is a kind of teaching horizontal projectile motion trajectory demonstration box of CN206497655U, devises one kind
The device of level throw motion is shown using the inertial flow of water, but due to apparatus structure complexity, and water cannot be changed
Flowing velocity can only see water and be moved along an angles and positions, more single uninteresting.
Invention content
The purpose of this utility model is to overcome above-mentioned technical disadvantages to provide a kind of horizontal projectile motion trajectory apparatus for demonstrating.Profit
It is acted on the elastic force of spring, different degrees of thrust can be generated to diving board, using on the graduation mark and fixed plate on telescopic rod
Time record display instrument, can not only record the time used in landing when being corresponded to each height by paraboloid, but also can be with needle
Different height and different spring thrusts are demonstrated, student is facilitated to calculate.
The utility model solve the technical solution that uses of technical problem for：A kind of horizontal projectile motion trajectory apparatus for demonstrating, including
Pedestal and fixed plate, the pedestal upper surface are provided with telescopic rod, and telescopic rod is fixedly connected with pedestal, the setting of telescopic rod excircle
Have a graduation mark, graduation mark facilitates student to calculate by the height of paraboloid, the fixed plate be located at telescopic rod upper surface and with stretch
Bar is fixedly connected, and fixed plate is internally provided with power supply, and fixed plate leading flank is arranged having time and records display instrument and switch, time note
Record display instrument is electrically connected between switch and power supply three, and time record display instrument is for recording and showing by paraboloid from opening
Beginning moves to the time of landing, and dead plate upper end face is provided with riser, spring and diving board, and diving board left side is provided with placement plate,
Placement plate is fixedly connected with diving board, and spring one end is fixedly connected with riser, and the other end is fixedly connected with diving board, riser and fixed plate
It is fixedly connected.
Advantageous effect possessed by the utility model is：The structure design of the utility model is reasonable, is made using the elastic force of spring
With, different degrees of thrust can be generated to diving board, utilize on the graduation mark and fixed plate on telescopic rod time record display
Instrument, can not only record the time used in landing when being corresponded to each height by paraboloid, but can be directed to different height and
Different spring thrusts are demonstrated, and student is facilitated to calculate.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the utility model.
Specific implementation mode
1 pair of the utility model is described below below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model includes pedestal 1 and fixed plate 6,1 upper surface of the pedestal is provided with telescopic rod 2,
Telescopic rod 2 is fixedly connected with pedestal 1, and 2 excircle of telescopic rod is provided with graduation mark 3, and graduation mark 3 facilitates student to calculate by paraboloid
Height, the fixed plate 6 is located at 2 upper surface of telescopic rod and is fixedly connected with telescopic rod 2, and fixed plate 6 is internally provided with power supply
11,6 leading flank of fixed plate is arranged having time and records display instrument 4 and switch 5, and the time records display instrument 4, switch 5 and power supply 11 3
It being electrically connected between person, time record display instrument 4 is used to recording and showing the time by paraboloid from setting in motion to landing, Gu
6 upper surface of fixed board is provided with riser 7, spring 8 and diving board 9, and 9 left side of diving board is provided with placement plate 10, placement plate 10 and diving board 9
It is fixedly connected, 8 one end of spring is fixedly connected with riser 7, and the other end is fixedly connected with diving board 9, and riser 7 is fixed with fixed plate 6 to be connected
It connects.
In use, the height of adjustable telescopic rod 2 first, then will be placed on above placement plate 10 by paraboloid, it is hand steered live
9 both sides of diving board and toward moving right, mobile distance can according to circumstances depending on, displacement distance is bigger, and the elastic force of spring 8 is bigger, separately
One hand is placed on above switch 5, is pressed lower switch 5 when the moment that hand decontrols diving board 9, is observed object of which movement process, until object is rigid
It falls to behind ground by lower switch 5.
