A physical model of the Sun can be represented by a computer program, a small yellow ball, or an equation describing the Sun's motion.
A physical model of the Sun can be represented by a computer program that shows how the Sun changes over time because it simulates the Sun's behavior and evolution based on scientific principles and data. Another example is a small yellow ball that represents the Sun, which can be used as a hands-on tool to demonstrate solar concepts visually. Additionally, an equation that describes the Sun's motion is a mathematical model used to study the Sun's movements.
