    • The physical reason for this is simple: At low sliding velocity the molecules in the liquidlike grafted film can "jump" out of their substrate pinning wells by thermal fluctuations, giving a small friction force. At high sliding velocity the molecules are pulled out of the pinning wells by the sliding motion (i.e., there is not enough time for them to get thermally depinned), giving rise to a much higher friction force. Recent experiments have indeed shown that the friction force between a gecko setae and a substrate increases monotonically with increasing sliding velocity [K. Autumn (private communication); see also Ref. 10].
