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.
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.

Coulomb damping absorbs energy with friction, which converts that kinetic energy into thermal energy, i.e. heat. Coulomb friction considers this under two distinct modes: either static, or kinetic. Static friction occurs when two objects are not in relative motion, e.g. if both are stationary. The force F s exerted between the objects does ...
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]
