law of coulomb frictioncoulomb in the year 1781 presented certain conclusions which are called as coulombs law of friction these observations are
kinetic dynamic frictionwhen applied force exceeds limiting friction the body starts moving over the other body and the friction of resistance
static friction when applied force is less than limiting friction body remains at rest and this type of frictional force is called as static friction
frictionwhen a body moves or tends to move over the other body a force opposing the motion develops at the contact surfaces this force that opposes
