Coefficient of friction physics history
WebThe coefficient of friction is the ratio of a force to a force, and hence has no units. Typical values for the coefficient of friction when sliding is occurring, i.e. the dynamic coefficient of friction are: for polished oiled metal surfaces, less than 0.1 for glass on glass, 0.4 for rubber on tarmac, close to 1.0 WebSep 28, 2024 · The coefficient of friction is a numerical value describing the resistance an object will be under as it tries to slide or slide across a surface. It is the ratio of the force …
