Abstract
The utility model discloses a device for demonstrating the trajectory of horizontal projectile motion. The device comprises a bracket formed by a vertical board (1) and a horizontal board (2) perpendicular to each other, wherein a cast platform (4) and a cast ball (5) adopting a magnetic body are fixed on the vertical board (1); a magnetic writing board (3) is additionally arranged on the vertical board (1); and a graduation line (6) for showing the height of a casting port is further marked on the cast platform (4). By adopting the device provided by the utility model, the trajectory of the cast ball (5) can be displayed clearly because the route of the cast ball (5) performing horizontal projectile motion is demonstrated via magnetic powder in the magnetic writing board (3).
Description
Technical field
The utility model belongs to teaching aid, more specifically to a kind of level throw motion track demonstration device.
Background technology
In level throw motion phenomenon and rule is an important content in middle school teaching stage, no level throw motion track demonstration device in the present teaching aid.
Summary of the invention
The purpose of this utility model provides a kind of level throw motion track demonstration device.
A kind of level throw motion track of the utility model demonstration device comprises the support of being made up of orthogonal erect plate and leveling board, the movement locus display, be fixed on the impelling platform on the described erect plate, the impelling ball has been added with magnetic on the described erect plate and has write plate, and described impelling ball is a magnetic.
The following beneficial effect of the utility model tool:
The magnetic that the described impelling ball warp place of mistake must have magnetic to write in the plate shows, thereby clearly illustrates that the impelling ball makes the track of level throw motion.
Description of drawings
Fig. 1 is the structural representation of a kind of level throw motion track of the utility model demonstration device.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in Figure 1, a kind of level throw motion track of the utility model demonstration device comprises the support of being made up of orthogonal erect plate 1 and leveling board 2, be fixed on the impelling platform 4 on the described erect plate 1, impelling ball 5 has been added with magnetic on the described erect plate 1 and has write plate 3, and described impelling ball 5 is magnetics.Described impelling ball 5 shows through the magnetics that the place must have magnetic to write in the plate 3, thereby clearly illustrates that impelling ball 5 makes the track of level throw motion.Also represent to have scale marks 6 on the described impelling platform 4 apart from how many height of impelling mouth.
Claims (1)
1. level throw motion track demonstration device, comprise the support of forming by orthogonal erect plate (1) and leveling board (2), be fixed on the impelling platform (4) on the described erect plate (1), impelling ball (5), it is characterized in that, be added with magnetic on the described erect plate (1) and write plate (3), described impelling ball (5) is a magnetic.
