If more surface area = more friction, than why do textured objects that have less surface area “cling” better?
In: Physics
They don’t, they have more traction, which is different than friction.
Friction doesn’t account for things bending or breaking when they come into contact, or the liquids or gases that might be trapped between two objects. A smooth tire on a wet road will have poor traction because it will ride on top of a layer of water. A tire with groves lets the water escape and maintains contact with the road.
