SUMMARY
The frictional force equation F = μN is distinct from F = mg(cosθ) due to the definitions of the forces involved. The frictional force F is calculated as the product of the coefficient of friction (μ) and the normal force (N), which is influenced by the object's mass, gravitational acceleration (g), and the angle of inclination (θ). The normal force is not solely dependent on gravitational force but also on any additional forces acting on the object, particularly in scenarios involving inclined or curved surfaces. Understanding these relationships is crucial for accurately calculating frictional forces in various physical contexts.
