Orbits & Gravity
Connect orbital patterns to conservation principles and gravitational dynamics across multiple systems.
A progression from descriptive orbital laws to dynamical causes, with enough depth for independent practice.
Instructions
Complete each required demo in sequence. Keep one running notebook with: - your prediction, - one measured observable, - one model-based inference.
Journey steps
-
Kepler’s Laws: Patterns of Planetary Motion
RequiredExtract orbital regularities from period, shape, and area patterns.
-
Conservation Laws: Energy & Momentum
RequiredUse energy/momentum conservation to explain trajectory changes.
-
Binary Orbits: Dynamical Reasoning Lab
RequiredInfer mass relationships from barycentric motion and velocity signatures.
-
Retrograde Motion: Apparent Longitude from Relative Motion
RequiredExplain apparent backward motion from relative orbital viewpoints.
Why this sequence?
Why this sequence?
Kepler supplies pattern language, conservation supplies mechanism, binary systems apply that mechanism to mass inference, and retrograde closes the loop with observer-centered apparent motion.
