What is the difference between static and kinetic friction?

Watch a video of me explaining the difference between static and kinetic friction by clicking here. Friction always acts in the direction opposite to the motion of the object. Just look at the direction the object is traveling. The direction of the force due to friction will be exactly 180° opposite.See all results for this questionWhat is the coefficient of friction?In physics, the coefficient of friction depends on the materials relative roughness ( 14) and if two contacting surfaces are involved, it is largely dependent on the absolute roughness of the individual surfaces ( 5 ). However, literature regarding the relationship of surface roughness and friction in orthodontic appliances has been inconclusive.See all results for this questionWhat factors affect the variation of friction?The variation of friction depends on interfacial conditions such as geometry, relative surface motion, surface roughness of contact surfaces, type of material, lubrication etc. Among these factors material and surface roughness are two major factors which play significant role for the variation of friction.See all results for this question
