Friction creates a force that resists motion between two contacting materials. When ignored, it can cause our mechanical design to fail. When understood correctly, it can be used to our advantage as we account for friction in moving parts and overcome its effects with proper lubricants. Some friction can be controlled and used to stop or increase motion. Many studies have been done to quantify the coefficient of friction for a large number of material types. This gives engineers the data we need to choose the best material for a frictional situation.
