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.

The abbreviation is not always a short form of the word used in the clue. For example: "Knight" for N (the symbol used in chess notation) Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE.
u is the flow velocity (in m/s), and ω is the vorticity (in s −1 ), defined as ω = ∇ × u . {\displaystyle {\boldsymbol {\omega }}=\nabla \times \mathbf {u} .} By using some vector calculus identities , these equations can be shown to result in Laplace's equations for the pressure and each of the components of the vorticity vector: [ 8 ]
where A and B are reactants C is a product a, b, and c are stoichiometric coefficients,. the reaction rate is often found to have the form: = [] [] Here is the reaction rate constant that depends on temperature, and [A] and [B] are the molar concentrations of substances A and B in moles per unit volume of solution, assuming the reaction is taking place throughout the volume of the ...
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]
