Physical ontology

Physical ontology is the study of physical things in the real world. It looks at the different types of things that make up the world, like animals, people, plants, rocks, oceans, mountains, and more. It also looks at how these things work together and interact with each other. Physical ontology tries to answer questions like "What is the name of this thing?", "What is it made of?" and "How does it interact with other things?"
