Demonstration device for physical education teaching

Abstract

The invention discloses a demonstration device for physics education teaching and relates to the technical field of physics teaching tools. The demonstration device comprises a demonstration box, wherein a straight plate I is fixed on one side of the upper part of the demonstration box; a radar speed tester is fixed in a position right aligned to the straight plate I on the other side of the demonstration box; a spring I is fixed on a side surface close to the part above the straight plate I, of the demonstration box; a baffle plate I is fixed at the tail end of the spring I; a pull rack is fixed on one side close to the spring I, of the baffle plate I; a fixing block is arranged on one side surface below the straight plate I, of the demonstration box; a transverse rod is fixed on the fixing block; a straight plate II is rotationally connected with the fixing block; a support rod is rotationally connected with the bottom surface of the straight plate II; the support rod is fixed with the transverse rod through a fixing clamp. By adopting the demonstration device, horizontal projectile motion and oblique projectile motion in physics teaching are very well demonstrated, students canunderstand and learn the principles conveniently, and in addition, the whole device is convenient to move, diverse in function and very applicable to physics education teaching demonstration.

Description

technical field [0001] The invention relates to the technical field of physics teaching appliances, in particular to a demonstration device for physics education and teaching. Background technique [0002] Physics is a subject that studies the most general laws of motion of matter and the basic structure of matter. As the leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, ranging from the universe to elementary particles, and thus becomes the research basis of other natural science disciplines. [0003] At present, in general physics teaching, teachers usually give teaching explanations directly on the blackboard. For some abstract physics content, it is not easy for students to understand, especially the content about material movement. Therefore, in order to facilitate students' understanding, improve Interest in learning physics requires a demonstration device for physics education and teaching. Contents of the...
