The friction coefficient is an empirical (experimentally measured) structural property that depends only on various aspects of the contacting materials, such as surface roughness. The coefficient of friction is not a function of mass or volume. For instance, a large aluminum block has the same coefficient of friction as a small aluminum block.

Pneumatic tribometer Static Friction Tribometer Hydrogen Tribometer. A tribometer is an instrument that measures tribological quantities, such as coefficient of friction, friction force, and wear volume, between two surfaces in contact. It was invented by the 18th century Dutch scientist Musschenbroek [1] [2]

Kinetic friction on the other hand, occurs when two objects are undergoing relative motion, as they slide against each other. The force F k exerted between the moving objects is equal in magnitude to the product of the normal force N and the coefficient of kinetic friction μ k: | | =. Regardless of the mode, friction always acts to oppose the ...
Sliding friction (also called kinetic friction) is a contact force that resists the sliding motion of two objects or an object and a surface. Sliding friction is almost always less than that of static friction; this is why it is easier to move an object once it starts moving rather than to get the object to begin moving from a rest position.

The coefficient of kinetic friction, , is less than the coefficient of static friction for both ice and snow. [9] [10] The force required for sliding on snow is the product of the coefficient of kinetic friction and the normal force: =. [11]
