🪐 Orbital Gravity - 2D Effective Potential, Kepler Orbits and Perihelion Shift

2D companion of the orbital gravity simulation: Kepler orbits from a symplectic integrator, the effective-potential well with turning points, equal-area sectors, vis-viva speed and a perihelion shift.

⚙ Under the hood

2D companion of the orbital gravity simulation: a symplectic integrator draws the orbit, the effective-potential well shows turning points, and Kepler's laws, vis-viva speed and a perihelion shift are checked numerically.
