AI overview
A physical object is something made of tangible materials—like matter or radiation—that exists as a unified thing with its own distinct properties. Understanding physical objects matters because they make up everything we can see and touch in the world around us, from everyday items to the building blocks of nature itself.

A bubble of exhaled gas in water In natural language and physical science, a physical object or material object (or simply an object or body) is a collection of matter, usually contiguous, with a defined boundary, that exists in space and time. It is usually contrasted with abstract objects and mental objects.
Also in common usage, an object is not constrained to consist of the same collection of matter. Atoms or parts of an object may change over time. An object is usually meant to be defined by the simplest representation of the boundary consistent with the observations. However the laws of physics only apply directly to objects that consist of the same collection of matter.
