Artificial Slope Structure for Physical Resistance Experimental Determination

Abstract

The invention provides an artificial slope surface structure for physical resistance experiment measurement,which comprises a base,an angle adjusting disc and a sliding block; an upward side guard board is fixedly connected with the front end and the rear end of the base respectively,a charging head is arranged in the front end plane of the side guard board at the front end of the base,and a datatransmission interface is arranged in the rear end plane of the side guard board at the rear end of the base. According to the invention,an inclined plate capable of ignoring force of friction,a first-stage friction bottom plate,a second-stage friction bottom plate and a third-stage friction bottom plate are arranged,and the friction resistance relationship among the first-stage friction bottom plate,the second-stage friction bottom plate and the third-stage friction bottom plate is 1-fold,2-fold and 3-fold sequentially,thereby being capable of forming a sharp contrast experiment at the time of performing the physical experiment,and facilitating accepting more vivid learning experience for students,regular growth of friction resistance facilitates summarizing various stress relationships on the inclined plate for the students.

Description

technical field [0001] The invention belongs to the technical field of physics teaching, and more specifically relates to an artificial slope structure used for physical resistance experiment measurement. Background technique [0002] In the existing physics teaching, in many cases, it is necessary to demonstrate to students in order to better combine classroom theoretical knowledge with practice, but there is no relatively complete demonstration teaching aid to demonstrate the various effects of objects on the slope. A physical phenomenon, such as the friction force of an object, the speed of motion, etc. At present, when teachers teach students on inclined planes, in order for students to understand physical phenomena more intuitively, they generally need to conduct experiments to enable students to observe intuitively. The general method is to find a suitable place or find different teaching tools to combine them with the function of demonstrating inclined planes. In thi...
