WebbCoefficient of Friction (COF) is defined as the friction force opposing sliding motion divided by the force normal to the surface. People walk differently (most people demand a consistent COF of between 0.25 – 0.3 walking normally) Long fast strides demand a higher friction. Although slippery surfaces or steep slopes provide low COF, we often ...

Webb2.1.1 Coefficient of friction measurement. Coefficient of friction (COF) is a dimensionless number that is defined as the ratio between friction force and normal force ( Eqn (2.1) ). Materials with COF smaller than 0.1 are considered lubricous materials. COF depends on the nature of the materials and surface roughness. WebbAfter performing this experiment, we needed to compute the angle (θ) at which the object starts slipping. Since we know the acceleration components: sin θ = a / g After calculating the different critical angles, the coefficients μ can be calculated as follows: N = mg cos θ f = mg sin θ = μN = μmg cos θ μ = tan θ
