Final answer:
To best support a reader's understanding of 'Roller Coaster Physics', an interactive model that highlights the scientific forces is the optimal choice because it allows for hands-on learning of physics principles in action.
Step-by-step explanation:
The question asks which of the provided options would best support the reader's understanding of the concepts presented in "Roller Coaster Physics". Considering the context, the most effective learning tool would be one that illustrates the physics concepts in action.
Analysis of Options
- A diagram of a roller coaster can show the structure and design, which helps visualize the physical aspects of a roller coaster.
- An advertisement for an amusement park is less educational and more promotional, which does not facilitate a deep understanding of physics concepts.
- An interactive model highlighting the scientific forces at work would provide a hands-on experience of how physics principles like potential energy, kinetic energy, and centripetal force come into play.
- A 3D video might be immersive, but it is less instructional compared to an interactive model.
Therefore, the most effective tool for supporting the understanding of roller coaster physics would be C: an interactive model highlighting the scientific forces at work.
