The friction is the phenomena that defines that there is a resistance which is present there between the two surfaces. This friction is applied tangentially to the surfaces in contact. Thus the main thing is that the forces on both of the surfaces act tangential to each other.

Frictional Force Direction
Frictional force always acts tangentially to the surface of the application of the friction. This means that the frictional force is parallel to the surface in contact.

Explanation
- When two surfaces are in contact and one surface moves or tends to move relative to the other, frictional force comes into play.
- The direction of the frictional force is always parallel to the surface of contact and opposite to the direction of motion or the tendency of motion.
- This tangential direction of frictional force helps in resisting the relative motion between the surfaces, preventing slipping or sliding.

Importance of Tangential Direction
- The tangential direction of the frictional force ensures that the surfaces in contact remain in contact and do not slide or slip past each other.
- It helps in providing stability and control in various mechanical systems where friction is utilized.
- Understanding the tangential direction of the frictional force is crucial in designing mechanisms that rely on friction for operation, such as brakes, clutches, and conveyor belts.
In conclusion, the frictional force always acts tangentially to the surface of the application of the friction, playing a critical role in maintaining stability and control in mechanical systems.
