Slipperiness

For other uses, see Slippery (disambiguation).

Slipperiness is when a surface has a low coefficient of friction, allowing objects to glide across the surface. People walking on slippery surfaces are likely to slip or fall. A surface can for example be slippery due to it being wet, or due to it being icy. There are several competing theories about why ice is slippery.
