Final answer:
Models are simplified representations that are true but ignore some aspects to make a complex system easier to understand, which is why this statement is true.
Step-by-step explanation:
Models are simplified representations of something and thus ignore important aspects of a situation. This statement is True. Models serve as a tool to simplify complex systems or objects for better understanding and analysis. In physics, models enable scientists to focus on specific aspects of a system without getting overwhelmed by its full complexity. For example, the Bohr model of the atom offers a simplified view of atomic structure, which helps explain some atomic behavior but is not a completely accurate depiction of an atom's intricate details. Models have limited validity and are useful for guiding our understanding within certain boundaries. They replace the real system by something similar but easier to examine, rather than being more detailed or universally valid.
