Description
Technical field
The utility model is related to physical teaching aid technical field and in particular to high school physicses parabola demonstration teaching aid.
Background technology
Object is dished out with certain initial velocity horizontal direction, if object is only subject to Action of Gravity Field, such motion is called flat
Throw motion.Level throw motion can regard the conjunction fortune of the linear uniform motion of horizontal direction and the movement of falling object of vertical direction as
Dynamic.The object of level throw motion, because suffered bonding force is constant force, so level throw motion is uniformly changed velocity motion, flat parabolic
The movement locus of body is a parabola.Level throw motion is the vertical height only with throw point for the time of curvilinear motion level throw motion
Relevant；Horizontal displacement and time that object lands（Vertical height）And horizontal initial rate is relevant, the direction of its velocity variations is all the time
It is straight down.
Physics lesson about parabolical teaching in, used to be all teach teacher on blackboard use pen one picture, or use
Computer is demonstrated, but always gives people one kind and less really feel.
Utility model content
The purpose of this utility model is the defect and deficiency for prior art, provides a kind of reasonable in design, structure letter
Single high school physicses parabola demonstration teaching aid.
For reaching above-mentioned purpose, the utility model employs following technical proposal：This high school physics demonstrates religion with parabola
Tool, it comprises parabolic platform, horizontal sliding rail, arc guide platform, lifting support, object disposing platform, Magnetic force ball, magnetic track
Capture board, reset magnetic bar；The upper end of described parabolic platform is provided with horizontal sliding rail, lives in the upper end of horizontal sliding rail
Move and be connected with arc guide platform, the upper end of arc guide platform is plugged with lifting support, and the top of lifting support is provided with puts
Thing platform, the upper surface of object disposing platform is provided with Magnetic force ball；The right side of described parabolic platform is connected with magnetic track capturing plate,
The back side of magnetic track capturing plate is provided with reset magnetic bar.
In above-mentioned high school physicses with, in parabola demonstration teaching aid, described reset magnetic bar passes through the activity of clamping chute even
It is connected on the back side of magnetic track capturing plate.
In above-mentioned high school physicses with parabola demonstration teaching aid, the arc chute lower limb of described arc guide platform
Upper surface flush with parabolic platform.
During the utility model operation, adjust the position of arc guide platform 3 and the height of object disposing platform 5 first, change magnetic
The outbound initial velocity of power ball 6, when Magnetic force ball 6 is after parabolic platform 1 flies out, Magnetic force ball 6 attracts in magnetic track capturing plate 7
Magnetic, formed parabolic motion track, carry out each item data of mechanics decomposition computation Magnetic force ball according to track
Compared with prior art, the beneficial effects of the utility model are：Its structure is simple, and design is new, flat using lifting
Platform coordinates arc guide platform to realize the change of Magnetic force ball initial velocity, adopts magnetic track capturing plate to catch the motion of spheroid simultaneously
Track, convenient and practical.
