Accompanying drawing explanation
Fig. 1 is the utility model stereographic map;
Fig. 2 is the utility model rear view.
In figure: 1, base 2, back up pad 201, groove 3, support column 4, connecting line 5, collision ball 6, swivel plate 601, turning axle 7, fixed head 701, fixed leg 702, pickup groove 8, fixed station 9, pilot lamp 10, stroke switch.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1 and Figure 2, a kind of novel senior middle school physics teaching teaching aid, comprise base 1 and back up pad 2, base 1 is provided with back up pad 2, back up pad 2 is provided with support column 3, support column 3 is provided with collision ball 5, collision ball 5 is connected on support column 3 by connecting line 4, back up pad 2 is provided with side and is provided with groove 201, in groove 201, be provided with swivel plate 6, the back up pad 2 of groove 201 side is provided with fixed head 7; Back up pad 2 opposite side is provided with fixed station 8, and fixed station 8 lower end is provided with stroke switch 10, and on fixed station 8, one end is provided with pilot lamp 9.
Arrange turning axle 601 in groove 201, turning axle 601 is arranged on swivel plate 6; Support column 3 is no less than 2, is provided with collision ball 5 at each support column 3; The distance of the center on swivel plate 6 and nearest support column 3 equals the spacing of colliding ball 5 and support column 3; Stroke switch 10 and the distance of nearest support column 3 equal the spacing of colliding ball 5 and support column 3; Support column 3 is on same horizontal linear; The back up pad 2 of the side of groove 201 is provided with pickup groove 702, in pickup groove 702, is provided with fixed leg 701, fixed leg 701 is provided with fixed head 7.
Collision ball 5 is placed on swivel plate 6, fixed head 7 is rotated on the upside of swivel plate 6, such maintenance swivel plate 6 level, when fixed head 7 rotates around fixed leg 701, fixed head 7 leaves from swivel plate 6, swivel plate 6, due to self gravitation, swivel plate 6 rotates around turning axle 601, collision ball 5 starts to fall, potential energy is kinetic energy, and collide other collision balls 5 in minimum point, momentum transmits mutually, collision ball 5 setting in motion of farthest, start kinetic energy to potential energy, finally encounter stroke switch 10, pilot lamp 9 lights; Can better demonstrate the law of conservation of momentum and the law of conservation of mechanical energy like this, due to reasons such as air resistance, low highly a little than turning axle 601 of fixed station 8; Ensure that the success ratio of experiment.
