A new feature of the rotating black holes is the existence in their ergosphere of trajectories of particles with negative and zero energies. Here we analyze general prop-erties of such trajectories comparing them with usual trajectories of particles with posi-tive energy. A comparison with the situation in rotating coordinate frame in Minkowski space-time is made. The possibility of the unbounded growth of the energy of two col-liding particles in the centre of mass frame in the ergosphere is analysed.
