Nucleus-nucleus interaction potentials and friction coefficients associated with one-body energy dissipation in the entrance channel of fusion reactions are extracted from the microscopic time-dependent Hartree-Fock theory. They show center-of-mass energy dependence close to the Coulomb barrier energy. This dependence indicates dynamical reorganization of internal degrees of freedom. We give a simple estimate of excitation energy from microscopic nucleon exchange.
