Abstract: A review of the many different factors influencing ice friction and their interdependence with respect to different friction regimes clarifies our understanding of the big picture of ice friction and sheds more light on the complexity of ice. Although the study of friction has a long history, ice friction has only been investigated during the last century. Underlying mechanisms of friction on ice are important to our understanding of glacial movements, cargo and ice breaker ship hull design, ice sports, and the grip of shoes and soles on icy roads. The basic physical concepts of boundary, mixed, and hydrodynamic friction apply to ice friction. However, these friction regimes must be described with respect to the thickness of the lubricating liquid-like layer on ice, as well as temperature of the ice, sliding velocity, the contact area between ice and slider, normal load exerted by the sliding object, relative humidity, and also properties of the slider material such as thermal conductivity, hydrophobicity, hardness and surface roughness.
