When two solid objects are rubbed together, kinetic friction occurs. This type of friction opposes the direction of motion between the surfaces of the objects and is caused by the microscopic interactions between the surfaces. The rougher the surfaces and the greater the force pressing the surfaces together, the stronger the kinetic friction.
