Abstract

The utility model patent relates to a six-sphere collision demonstration instrument, which is composed of six identical elastic spheres, compression springs, thin wires and brackets, and is characterized in that six identical elastic spheres are vertically suspended on the same bracket through thin wire Above, the elastic sphere and the thin wire are in the same vertical plane, the centroids of the elastic sphere are on the same horizontal line, the two elastic spheres in the middle are connected horizontally by the compression spring, and the other adjacent elastic spheres just touch. During the experiment, one or two elastic spheres on the left were pulled in turn and released at the same time, and watching the changes of other elastic spheres and compression springs was helpful to correctly understand the conversion of kinetic energy and potential energy of elastic bodies during the collision process. The design of the utility model patent is easy to realize, Low cost and easy operation, combined with teaching to allow students to participate in practice, will greatly improve the learning effect of students.

Description

A six-sphere collision demonstration instrument

technical field

The utility model patent relates to a six-sphere collision demonstration instrument, which belongs to the field of physics demonstration instruments.

Background technique

The collision of elastic bodies is a very important content in college physics teaching. In order to demonstrate in class and after class, people give a horizontal equal mass multi-sphere collision instrument. Teacher Liang Faku and Professor Lu Junling of Tsinghua University etc. in "Teaching Instruments "Equal Mass and Increasing Mass Sphere Collision Apparatus" in the second issue of 2007, and the Chinese patent "Elastic Collision Demonstration Device" CN200720123023 in 2007 provides the experimental design of the collision of spheres with equal decreasing mass, which play a role in teaching. Active promotion, these only give a demonstration of part of the collision law, the moment of collision is short, the lack of collision process, the conversion of kinetic energy into potential energy during the compression process of the sphere, and the obvious phenomenon of potential energy conversion into kinetic energy during the recovery process, it is not easy to understand the collision process understanding of the mechanism. How to design a demonstration instrument with simple structure, low cost, easy implementation and obvious effect, this patent will solve this problem.

Contents of the invention

The utility model patent solves a six-sphere collision demonstration instrument, emphatically solving the technique of using a compressed spring and six equal-mass elastic spheres to realize the demonstration of the elastic sphere collision law.

The utility model patent technical scheme: a six-sphere collision demonstration instrument is composed of 6 identical elastic spheres, compression springs, thin wires and brackets, and is characterized in that: 6 identical elastic spheres are vertically suspended on the ground through thin wires On the same support, the elastic spheres and thin wires are in the same vertical plane, the centroids of six identical elastic spheres are on the same horizontal line, the two elastic spheres in the middle are horizontally connected by compression springs, and other adjacent elastic spheres just touch. During the experiment, pull one and two elastic spheres on the left and release them at the same time, watch the changes of other elastic spheres and compression springs, and let students participate in practice, research and analysis in combination with teaching, which will greatly improve the learning effect of students.

The design of the utility model patent is easy to realize, low in cost and easy to operate, and it will be more conducive to developing students' innovative thinking and practical ability when used in college physics teaching.
