Physics
Physics (物理学) is the study of mathematics to explain the motion of objects and how energy is transmitted.
Overview
Physics (物理学/ぶつりがく, Butsurigaku) is the study of mathematically clarifying the behavior of energy, such as the movement of objects, electromagnetic waves, and sound.
Since everything that exists in the world (and even things that are unknown whether they exist in the world or not) can be the subject of physics, there is no end to the detailed classification of the subject.
