What Is Static Friction? | Reference.com

Lubrication often lowers the coefficient of static friction of a pair of materials. For example, The coefficient of static friction between dry concrete and rubber is 1.0 but decreases to 0.30 when wet, resulting in a more slippery surface. Rolling friction occurs when one object rolls across the other.

Rolling resistance - Wikipedia

Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc. is recovered when the pressure is removed.
