Physical models are tangible representations of objects or systems that help us understand complex concepts. They can be simple, like a globe representing the Earth, or intricate, like a scale model of a building. These models allow scientists, engineers, and students to visualize and manipulate elements that may be difficult to observe directly. In various fields, such as architecture, biology, and physics, physical models serve as valuable tools for experimentation and education. They can illustrate processes, demonstrate relationships, and predict outcomes, making abstract ideas more accessible and easier to grasp for learners and professionals alike.
