Definition
The coefficient of kinetic friction is a value that represents the amount of force required to keep two surfaces sliding against each other at a constant velocity.
The coefficient of static friction is a value that represents the amount of force needed to overcome static friction and initiate motion between two surfaces.
Normal Force: The normal force is the perpendicular force exerted by a surface on an object in contact with it.
