Friction Force: Definition, Formulas - a Simple Explanation

Webμ s is the static coefficient of friction and N is the normal force. The normal force equals the car’s weight on level ground, so N = m g. Thus the centripetal force in this situation is F c ≡ f = μ s N = μ s m g. Now we have a relationship between centripetal force and the coefficient of friction. Using the equation F c = m v 2 r, we obtain WebSep 12, 2024 · A minimum coefficient of friction is needed, or the car will move in a larger-radius curve and leave the roadway. Strategy We know that Fc = mv2 r. Thus Fc = mv2 r = (900.0kg)(25.00 m / s)2 (500.0m) = 1125N. Figure 6.6.2 shows the forces acting on the car on an unbanked (level ground) curve.
