What This Document Is
This is a worksheet designed to accompany Lesson 4 of the PHYS 1404 Solar System course at Central Texas College. It focuses on applying Kepler’s Laws and Newtonian physics to understand planetary motion using the NAAP Planetary Orbit Simulator. The worksheet is a lab activity intended for student completion.
Why This Document Matters
This worksheet is for students enrolled in PHYS 1404 who are learning about orbital mechanics. It’s used as a hands-on exercise to reinforce concepts presented in the course materials. Successful completion demonstrates understanding of Kepler’s Laws and Newton’s Law of Universal Gravitation in the context of planetary orbits.
Common Limitations or Challenges
This worksheet requires access to the NAAP Planetary Orbit Simulator, which is a separate software component. The worksheet itself does not *teach* the underlying physics; it assumes prior learning from the course’s background materials. It’s a tool for practice and assessment, not a standalone learning resource.
What This Document Provides
The full document includes:
* Conceptual questions testing understanding of Kepler’s Laws and Newton’s First Law.
* Instructions for using the NAAP Planetary Orbit Simulator.
* Exercises requiring manipulation of orbital parameters (semi-major axis, eccentricity) within the simulator.
* Questions asking for specific values (r<sub>p</sub>, r<sub>a</sub>) derived from the simulator.
* A sketching exercise to visualize elliptical orbits.
This preview only provides a description of the document’s contents and purpose. It does *not* include the answers to the questions or a walkthrough of the simulator exercises.
