The physical side refers to the tangible or material aspects of something, as opposed to its intangible or abstract qualities. It can refer to the concrete, visible, and touchable elements of an object, person, place, or thing, as well as the practical, hands-on aspects of a task, process, or activity. In other words, it is concerned with what we can see, hear, taste, smell, and feel, rather than what we cannot experience through our senses.
