Abstract
摩擦力是一种常见的力,同时也是一种多因素共同决定的力.很多人认为摩擦力的概念抽象而不容易理解,尤其是摩擦力的大小与接触面的关系问题.为了辅助摩擦力教学,设计了一台摩擦力演示装置.同时介绍了该演示装置的设计原理、装置构成、制作方法以及仪器的详细使用方法.它适用于学生做基础的摩擦力验证实验.
Friction is a common force and also a force determined by multiple factors.Many people feel that the concept of friction is abstract and difficult to understand,especially the relationship between the magnitude of fric-tion and the contact surface.In order to assist the teaching of friction,the author designed a friction demonstration device.The article mainly introduces the design principle,device composition,production method and detailed us-age method of the demonstration device.It is suitable for students to conduct basic friction verification experiments.
