Problems solved by technology

"Many students find it difficult to understand, and teachers also lack vivid teaching demonstration instruments when explaining
[0004] 2. According to the students' hobbies, in the popular science lectures on the history of modern physics and the theory of relativity for some students in ordinary high schools, due to the lack of teaching demonstration equipment and the limitations of students' cognitive level, students lack imagination about the space curvature of general relativity , it is difficult to understand the theory; students' awareness of scientific inquiry needs to be further improved

Abstract

A space curving model demonstrator utilizes warping of a rubber membrane to vividly analog a curved space caused by gravity, and simulates and demonstrates difference between ball body moving trajectories when a moving ball body passes through a flat space without a gravitational field and a curved space with a gravitational field respectively, so as to show the existence of the gravitational field, that is, the space around the gravitational field is curved. The space curving model demonstrator has the advantages of simple structure, convenient operation, high visibility, visual and obvious phenomenon, low cost, safe demonstration, durable property, and easy popularization.

Description

technical field [0001] The invention relates to a space bending model demonstrator, which belongs to a teaching instrument, in particular to a space bending model demonstrator which utilizes rubber film warping to imagine and metaphorize the space bending caused by gravity. Background technique [0002] General relativity is a gravitational theory described in geometric language published by Einstein in 1916, which represents the highest level of gravitational theory research in modern physics. The general theory of relativity includes the classic Newton's law of universal gravitation in the framework of the special theory of relativity, and is established on this basis by applying the principle of equivalence. Einstein's general theory of relativity gives the relationship between space-time and matter and their laws of motion. The curved nature of space-time depends on the distribution and motion of matter. Gravity is described as a geometric property (curvature) of space-t...
