A magnetic levitation guide rail used for verifying momentum conservation law in high school physics

Abstract

The invention discloses a magnetic levitation guide rail used for verifying momentum conservation law in high school physics, belonging to the technical field of high school physics experiment equipment. The magnetic levitation guide rail includes a base, the upper end of the base is fixedly connected with a fixed guide rail, the fixed guide rail is sleeved with a pair of sliding blocks matched with the fixed guide rail, the two sliders have the same mass, There is a gap between the stationary guide and the slider, the lower end of the fixed guide rail is fixedly connected with a pair of firstsuspension magnets, the slider is fixedly connected with a second suspension magnet matched with the first suspension magnet, the principle of magnetic levitation can be realized, The invention replaces the air cushion guide rail of the external air pump in the high school experiment, is simple in operation and convenient in handling, solves various complicated assembly steps of the air pump usedin the prior art to a great extent, eliminates various potential safety hazards, greatly improves the teaching efficiency of teachers, and facilitates students to learn knowledge through the experiment quickly and accurately.

Description

technical field [0001] The invention relates to the technical field of high school physics experiment equipment, more specifically, relates to a magnetic levitation guide rail used for high school physics verification of the law of conservation of momentum. Background technique [0002] The law of conservation of momentum, the law of conservation of energy and the law of conservation of angular momentum together become the three basic laws of conservation in modern physics. At first they were corollaries of Newton's laws, but later it was found that their scope of application was far wider than Newton's laws, and they were more fundamental physical laws than Newton's laws, reflecting the nature of space and time. The law of conservation of momentum is one of the most important and universal laws of conservation in nature. It applies to both macroscopic objects and microscopic particles; In unclear problems, the law of conservation of momentum also applies. [0003] Air-cus...

Problems solved by technology

[0004] The purpose of using the air cushion guide rail is to reduce or even eliminate the friction between the guide rail and the slider during the experiment, so as to make the experimental results more accurate. The existing air cushion guide rails need to cooperate with the input of the air source. The air pump and the air cushion guide rail need a relatively airtight connection, which is prone to air leakage during use, and the external air pump is a safety risk during the experiment, and it is very inconvenient to carry it back and forth, and it will waste a lot of precious time if it needs to be assembled and debugged , so that many schools do not use the air pump directly in the actual teaching, which will affect the teaching effect and is not conducive to students' quick and accurate understanding of the essence of the experiment
