Newtonian mechanics#

Vector dynamics under a force: free fall with an oblique launch velocity (ProjectileMotion) and the 2-body Kepler problem (KeplerSystem), including the post-Newtonian and power-law perturbations that make orbits precess, plus a pendulum viewed from Earth’s rotating frame (FoucaultPendulum), whose Coriolis-driven swing-plane precession demonstrated that rotation directly.
