A bookbag is considered matter because it has mass and occupies space, which are the two defining characteristics of matter. Made from materials like fabric, plastic, or leather, it consists of atoms and molecules. Additionally, it can interact with other physical objects and can be perceived through our senses, further affirming its status as matter.
