Friction mu
WebThe coefficient of friction (COF) is a number that determines the amount of friction between materials in contact. It is often designated by the Greek letter mu ( μ ). In most cases, the COF is also independent of the area of the surfaces in contact. WebSep 12, 2024 · where \(\mu_{s}\) is the coefficient of static friction and N is the magnitude of the normal force. The symbol ≤ means less than or equal to , implying that static friction can have a maximum value of \(\mu_{s}\)N. Static friction is a responsive force that increases to be equal and opposite to whatever force is exerted, up to its maximum limit.
