The dry friction is acted upon the surfaces. And they are tangential to each other. As we know the friction is the phenomena that defines that there is a resistance which is present there between the two surfaces. The dry friction is also termed as the Coulomb friction as it was given by C.A. Coulomb.

Coulomb Friction is also called Dry Friction.
Explanation:
Dry friction is a force that opposes the relative motion between two solid surfaces in contact. Coulomb friction is a type of dry friction that occurs when there is no lubrication between the two surfaces. It is named after Charles-Augustin de Coulomb, a French physicist who first described this type of frictional force.
Coulomb friction is characterized by a constant friction coefficient that remains the same regardless of the speed or direction of relative motion between the surfaces. This coefficient is dependent on the nature of the surfaces in contact, their roughness, and the normal force pressing them together.
The term "dry friction" is often used interchangeably with Coulomb friction because it is the most common type of friction encountered in everyday life. However, there are other types of friction, such as fluid friction and rolling friction, that do not fall under the category of dry friction.
In conclusion, Coulomb friction is a specific type of dry friction that is characterized by a constant friction coefficient. It is commonly referred to as "dry friction" because it is the most common type of friction encountered in daily life.
