Orbits in inverse-square potential

Attractive force Orbits with same angular momentum but different energies
Orbits with same energies (positive) but different angular momenta start of orbit (up to point of closest approach)
Orbits with same energies (positive) but different angular momenta complete orbit
same, but with more incoming trajectories
complete orbit
Repulsive force identical initial conditions
Repulsive force energy four times as big
Repulsive force energy sixteen times as big
Repulsive force equally spaced incoming conditions
Repulsive force equally spaced incoming conditions energy four times as big
Repulsive force equally spaced incoming conditions energy sixteen times as big
Repulsive force equally spaced incoming conditions energy 64 times as big
