物理

1. Origins, structure, and basic meaning

• Structure: 物理, read ぶつり, means physics in these examples: the study of laws governing natural phenomena.
• Basic usage: It is a noun naming a school subject or a field used to explain phenomena.

2. Common pitfalls and similar expressions

• Field and content
  • 物理の基礎 means the basics of physics.
  • 物理の法則で説明した says the phenomenon was explained using the laws of physics as the basis or means.
• Noun and modifier
  • Do not treat 物理 itself as an adjective simply because English has 'physical.' An adjectival expression can take a form such as 物理的な.
