If the energy of the planet is negative, it's moving along the ellipse, if it's positive or zero, it's hyperbolic or parabolic motion. It's easy with planets, because $E = T + V$ and here the potential energy $V$ is stronger than kinetic energy $T$. Remember $V \sim -r^{-1}$. If the body has positive energy, it means it has energy to beat the potential of the sun and fly away. In atoms we don't assume parabolic, hyperbolic or elliptic motions, but the energy idea is the same. | |
