What two advantages and two limitations of physical models?

Two advantages of physical models are that they provide a tangible representation of concepts, making complex ideas easier to understand and visualize, and they allow for hands-on experimentation, which can enhance learning and engagement. However, two limitations are that physical models can be expensive and time-consuming to create, and they may not always accurately represent the intricacies or scale of the systems they depict, leading to potential misunderstandings.
