SUMMARY
The discussion clarifies the distinction between resistance force and friction coefficient. Resistance force refers to the total force opposing motion, which includes frictional resistance, while the friction coefficient is a dimensionless ratio representing the relationship between frictional force and normal force, expressed as \(F_{friction} = \mu N\). The friction force is measured in Newtons, whereas the friction coefficient is unitless. Additionally, calculating the friction coefficient is complex due to its dependence on various factors such as surface cleanliness and temperature.
