WebApr 11, 2024 · How to calculate the Force of Friction. Calculate the force of friction using the formula: F = μn. Where N is the normal force and μ is the friction coefficient for your tools and whether they are stationary or moving. The normal force is equivalent to the weight of the object, so this can also be written as: F = μmg. WebStatic friction prevents sliding. Static friction is the force holding an object in place on an incline, such as the cheese in Figure 1. The friction force points against the direction … cgh employment
