The formula to calculate the Coefficient of Friction (μ) is:
\[ μ = \frac{F}{N} \]
Where:
A coefficient of friction is defined as the unitless factor between two surfaces that resist movement when under a normal force. This can be used in both static and kinetic friction cases. In a static friction case, the force applied, \( P \), will never exceed the frictional force \( F \). Otherwise, the object would be in motion and this would be a kinetic friction case.
Let's assume the following values:
Using the formula to calculate the Coefficient of Friction:
\[ μ = \frac{30}{50} = 0.60 \]
The Coefficient of Friction is approximately 0.60.
