物理（ぶつり、butsuri）
- physics

The Japanese word 物理, pronounced ぶつり (butsuri), primarily translates to "physics" in English. It refers to the branch of science concerned with the nature and properties of matter and energy. This includes the study of motion, forces, energy, and the fundamental constituents of the universe. It can also be used in a broader sense to refer to the physical world or the properties of something physical.

⚫︎彼は大学で物理を専攻しています。 Translation: He is majoring in physics at university. ⚫︎その実験は物理の法則に従っています。 Translation: That experiment follows the laws of physics. ⚫︎この現象は物理的に説明できる。 Translation: This phenomenon can be explained physically.

You use 物理 when discussing the science of physics, related concepts, or the physical properties of objects. It is appropriate in academic settings, when talking about scientific principles, or when describing the physical nature of something. The context usually makes it clear whether you are referring to the subject of physics or the physical aspects of something.

⚫︎The word is typically written in kanji as 物理. ⚫︎The reading is ぶつり in hiragana. ⚫︎There are no variations in okurigana for this word.

There are no direct synonyms for the subject of "physics" in Japanese, as 物理 is the standard term. However, you might use more descriptive phrases depending on the specific aspect of physics you are discussing, such as 力学(rikigaku - mechanics), 電磁気学(denjikigaku - electromagnetism), or 量子力学(ryousikigaku - quantum mechanics).

The antonyms are not directly applicable. If you are comparing 物理 to other subject areas, you might contrast it with something like 化学(kagaku - chemistry), 生物学(seibutsugaku - biology), or 哲学(tetsugaku - philosophy) depending on the context.

The word 物理 is a compound word derived from two kanji: 物(mono) which means "thing" or "matter," and 理(ri) which means "logic," "reason," or "principle." Together, 物理 signifies the "principles of things" or the study of the nature of matter and its properties, leading to the meaning of "physics".
