Types of Extraction

Methods of extraction Many metals are found in the Earth's crust as ores An ore is usually a compound of the metal mixed with impurities When the metal is dug up a method must be used to separate the metal from the rest of the ore This is called extracting the metal The method of extraction depends on how reactive the metal is The more reactive the metal the more difficult it is to Get price

Friction and Friction Coefficients

The friction force is the force exerted by a surface when an object moves across it - or makes an effort to move across it The frictional force can be expressed as F f = μ N (1) where F f = frictional force (N lb) μ = static (μ s) or kinetic (μ k) frictional coefficient N = normal force between the surfaces (N lb) There are at least two types of friction forcesGet price
