calculating the friction force for static object. The formula is fr = mu * N, where the mu is the coefficient of friction which incorporating the characteristics of the surface. For example, if you want to calculate the friction when you put your phone on a table, then the coefficient of friction is depending on the matirial of the table. N is the normal force which means the perpendicular force of the surface which object touching on. In our case, it would be m*g since it is on the ground. fr = mu * m * g.
