Physical (Material) refers to anything that has mass and occupies space. This includes all tangible objects, such as rocks, water, and trees. Physical materials can be classified into different categories, such as solids, liquids, and gases, based on their state and properties. In science, the study of physical materials involves understanding their composition, structure, and behavior. This includes examining how materials interact with each other and their environment. For example, metals are known for their strength and conductivity, while plastics are valued for their versatility and lightweight nature.
