In this contribution we present the one-body dissipation dynamics in the fully three-dimensional time-dependent Hartree-Fock (TDHF) theory. The calculations were performed with modern Skyrme energy functionals plus tensor terms and without any symmetry restrictions. The energy dissipation was revealed to decrease in deep-inelastic collisions of the light systems as the bombarding energy increases owing to the competition between collective motion and single-particle degrees of freedom. The role of spin-orbit and tensor force was given particular emphasis. The spin-orbit force causes a significant enhancement of the dissipation. About 40%~65% of the total dissipation depending on the different parameter sets was predicted to arise from the spin-orbit force. The fusion cross section without tensor force overestimates the experimental value by about 25%, while the calculation with tensor force T11 has a good agreement with experimental cross section.
