WebMar 31, 2024 · Force from friction between two objects is calculated as it would be in any other situation - via the following equation: Force due to friction (usually written F r) = (mu)N, where mu is the friction coefficient between the two objects and N is the normal force between the two objects, or the force with which they are pressing into each other. WebIf the coefficient of friction is 0,3, find the acceleration of the box. Free body diagram of the system is given above. From this diagram we find the normal force of the surface and friction force. Fnormal=mg-Fy Fnormal =60N-40N=20N And friction force is; Ffriction=µ.Fnormal=0,3.20N=6N
