Abstract

The invention belongs to the technical field of teaching equipment and provides a parabolic demonstration teaching aid for colledge mathematics teaching which comprises a fixed plate, a connecting plate, a rotary table, a launching barrel, a controller and a computer. The bottom end of the fixed plate is vertically provided with a groove, the groove is arranged inside the fixed plate, a through hole is uniformly arranged on the front end surface of the fixed plate, and a magnetic switch and an LED lamp are arranged in the through hole. The rotary table is rotatably mounted on the connecting plate through a first rotating shaft, and the rotary table can rotate in the vertical plane of the connecting plate; The launching barrel is rotatably mounted on the rotary table through the second rotating shaft, the launching barrel is used for ejecting the steel ball, a launching unit is arranged in the launching barrel, the launching unit is used for ejecting the steel ball in the launching barrel, and the steel ball moves in a parabolic trajectory in the groove of the fixing plate; the second rotating shaft is fixed on the upper end of the firing barrel, and the axis of the rotating shaft2 is located in the horizontal plane where the end face of the opening of the firing barrel is located. The invention ensures the precise adjustment, realizes the control of a single variable, and improves the scientificity of analysis and research.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, in particular to a parabola demonstration teaching aid for university mathematics teaching. Background technique [0002] In a plane, the locus of a point whose distance from a fixed point is equal to a fixed line is called a parabola. At present, when teaching mathematics, the teacher needs to explain to the students how the formation process of the parabola is reflected through mathematical expressions. Due to the specific abstraction of mathematical thinking and the different understandings of different students, in teaching In the process of learning, it is often encountered that some students need to explain many times in the chapter of parabola, in order to understand roughly how objects form a parabola through the movement of internal relations. The existing demonstration device is simple and impractical, and the experiment process is greatly affected by the outside world, maki...
