Embodiment
The technical solution of the utility model, a kind of Galilean obliquity experiment demonstrator, its feature is described in detail with reference to accompanying drawing
It is：
Including demonstration iron ball 1, supporting mechanism and demonstration mechanism, the supporting mechanism includes platform 3 and is arranged at platform bottom
Portion both sides are used for the support 2 of support platform, and the demonstration mechanism includes concave tracks 5 made of plastic material, electromagnet 7, speed
Platform upper surface, concave tracks two are fixed in degree inductor 13, inductor 11 and regulating bolt 10, the concave tracks bottom
End is provided with the left straight rail 6 and right straight rail 4 tangent with its top, the concave tracks, left straight rail and right straight rail two
Side is fixed with iron ball baffle plate 17, and the long groove for prolonging the distribution of its length direction is provided with the iron ball baffle plate of the side, described
The symmetrical long recess for prolonging the distribution of its length direction is provided with the iron ball baffle plate of opposite side, is fixedly installed on the long groove
Multiple seamless light sensors 12 being mounted side by side, it is fixedly installed on the long recess multiple corresponding with light sensor
LED small bulbs 8, the electromagnet is fixed on the bottom on left straight rail top, and the inductor is arranged at the bottom of concave tracks
The inside in portion, the inductor are connected by circuit with timer 9, and the electromagnet and timer pass through same two-way control
System switch is connected with power supply, and the speed sensor is arranged at the top of right straight rail, and the speed sensor passes through circuit
It is connected with display screen 14, the regulating bolt is symmetricly set in the side bottom of concave tracks two, and the screw rod of the regulating bolt is worn
The tapped through hole crossed on base is fixedly connected with concave tracks, and the demonstration iron ball can be adsorbed by electromagnet is fixed on left straight rail
