Lifting type acceleration and path relation demonstration apparatus for physics teaching in middle schools

Abstract

The invention discloses a lifting type acceleration and path length relation demonstration apparatus for physics teaching in middle schools. The lifting type acceleration and path relation demonstration apparatus comprises a horizontal bracing frame, and two rotary supporting rods installed on base body of a mounting base. The top end of a rod body of a telescopic adjusting rod is connected with the rotary supporting rods through lifting auxiliary rotary shafts, and an inclined disposing plate is hinged to the right side above the plate body of a demonstration operation desktop through a fourth rotary shaft. A fan-shaped plate is arranged on the sidewall of the plate body of the inclined disposing plate, a heavy plummet head is fixedly arranged on the bottom end of a fine pulling rope, and a stopwatch is arranged on the plate body under the left end of the demonstration operation desktop. The relation between acceleration and path length can be obtained through related calculation, so that students can know better for actual parameters. The demonstration height of the demonstration operation table can be stably adjusted, and use effect is good.

Description

technical field [0001] The invention relates to the related technical field of teaching aids, in particular to a lifting-type middle school physics teaching demonstration device for the relationship between acceleration and distance. Background technique [0002] Junior high school physics is a basic subject of compulsory education, and this course is generally offered from the second year of junior high school; physics comes from life and is also applied to life. The main purpose of our learning physics knowledge is to use physics knowledge to explain various phenomena in life, and to Use physical knowledge to analyze the causes of various problems, so as to find out the methods and measures to solve related problems. If the society wants to progress, the development of science and technology is the first thing. Another important purpose of learning physics is to master and understand physics knowledge, to be able to flexibly use this knowledge to innovate, to explore unkno...

AI Technical Summary

Problems solved by technology

In the learning process of middle school physics, parameter data such as speed, acceleration, and distance have always been the key learning content. The previous teaching method was carried out in books, resulting in a very abstract form of motion. It is difficult for students to understand this problem, resulting in students They are very ineffective in school, and the knowledge they have learned is difficult to understand deeply, which requires a specific demonstration device to solve this problem
