A kind of friction physics experiment method

Abstract

The invention relates to the field of physics teaching and in particular provides a friction force physical experiment method. Friction force physical experiment teaching tools used by the method comprises a box body, an ejection mechanism, a storage mechanism, a detection mechanism, a blocking plate, a rubber cushion, a conveying plate and small balls. The three small balls can be ejected once and the operation of three sides can be completed at a time, so that students can understand the influence of friction coefficients on movement directly according to the position difference among the small balls; applied force can be reduced gradually to make the small ball in a later test move to the position behind the small ball in the previous test, so that students can understand the influenceof force on movement through the distance between the two balls on the same detection slide plate and further determine the influence of friction force on movement through the position difference of balls on difference detection slide plates; the small balls can fall to the ejection position automatically, so that the operation process is more simple; when a ball is ejected, another ball will fallto the bottom of a storage tube automatically, so that students do not need to add balls.

Description

technical field [0001] The invention relates to the field of physics teaching, in particular to a friction physics experiment method. Background technique [0002] In physics teaching, experiment is a very important teaching method. When teaching friction, it is necessary to let students understand the influence of force and friction system on motion through experiments. [0003] When the current friction physics experiment demonstration teaching aid is in operation, a student needs to pull the spring handle, a student puts the slider in the pop-up position, conduct an experiment, and then the student records the relevant data, and the student needs to repeatedly place the ball and pull the spring The handle is very laborious and cumbersome to operate; when comparing different friction coefficients, multiple sets of experiments need to be carried out, and students need to record a lot of data, the display of the influence relationship is not obvious enough, and it is easy to...
