We have developed the measuring system of the energy dissipation due to the dynamical frictional force at a small contact. The system is consisted of a combined atomic force microscope(AFM) with a quartz crystal microbalance(QCM) resonator. We measured the dynamical frictional force acting on graphite and C60 substrates with the AFM tip, and found that the force does not depend on the sliding distance in the case when the sliding distance is larger then the lattice constant, while it is proportional to the sliding distance at a small sliding distance.
