匀加速运动,特别是匀加速直线运动,一般都认为是运动学中最简单最基本的问题,因此,有关这一运动形式的一些很基本的理论问题常常被忽视。本文拟从匀加速直线运动这一简单的经典问题出发,通过对匀加速运动普遍公式的导出及讨论,从基本物理意义上作了较为深刻的阐述;特别从知识结构上,由匀加速运动的概念及公式推导,到匀加速直线运动、匀加速曲线运动和一些特殊的曲线运动,作了较为深入的讨论。这对于学生弄清知识结构,系统地掌握物理知识,提高运用数学知识解决物理问题的能力,培养思维能力和辩证唯物主义观点,是会有所帮助的。
Uniform acceleration, especially uniform acceleration linear motion, is generally considered to be the simplest and most basic problem in kinematics. Therefore, some very basic theoretical questions about this form of motion are often overlooked. Based on the simple classical problem of accelerating linear motion, this paper elaborates the derivation and discussion of the universal formula of uniform accelerating motion from the perspective of basic physics. Especially from the perspective of knowledge structure, Concept and formula derivation, to uniform acceleration linear motion, uniform acceleration curve motion and some special curve motion, made a more in-depth discussion. This will be helpful for students to understand the structure of knowledge, systematically master the knowledge of physics, improve the ability of using mathematical knowledge to solve physical problems, cultivate the thinking ability and dialectical materialism.
