相对与绝对是两个相关联的词语。相对,有条件、有限制、有依赖关系的随条件的变化而起变化的,叫相对。绝对,无条件的、永恒的、无限的意思。世界上一切事物既包括相对的方面,又包括绝对的方面,相对中包含着绝对,绝对存在于相对之中。相对和绝对是辩证统一。在哲学上是这样,在中学物理中也常用到相对与绝对这两个词。本文从力学、热学、电学、光学和近代物理学几方面简述中学物理中常提到的相对与绝对。
Relative and absolute are two related terms. Relative, conditional, limited, dependent changes with conditions change, called the relative. Absolute, unconditional, eternal, unlimited meaning. Everything in the world includes both relative aspects as well as absolute aspects, while relative content contains absoluteness and absoluteness in relative terms. Relative and absolute dialectical unity. This is philosophical, and the two terms relative and absolute are also commonly used in high school physics. In this paper, we briefly summarize the relativity and absoluteness often mentioned in middle school physics from the aspects of mechanics, heat, electricity, optics and modern physics.
