 For the figure on the right, the total energy is positive and hence, even at infinite distance, the less massive object has non-zero kinetic energy. This is an **unbound system** because the less massive object can move infinitely far away from the more massive object. For the figure on the right, the total energy is positive and hence, even at infinite distance, the less massive object has non-zero kinetic energy. This is an **unbound system** because the less massive object can move infinitely far away from the more massive object.

 For an **unbound system** the kinetic energy levels off to the value of the total (positive) energy of the system. When the less massive object is infinitely far away, the potential energy of the system goes to zero. For an **unbound system** the kinetic energy levels off to the value of the total (positive) energy of the system. When the less massive object is infinitely far away, the potential energy of the system goes to zero.
