Quora User is correct about the two different phenomena. On the second case I have to add that the exact mechanism by which moisture usually increases friction is the capillary force, which produces what is called the "meniscus effect". read more

When one surface is kept over another its electrons attract the protons of another and there is a force of attraction .So when body is displaced the protons and electrons attract each other leading to slowing down of the object and so this is the cause of friction. read more
Best Answer: Water does reduce friction and does cause greater speed (e.g going down a water slide with water vs going down one without). Water reduces the effects of friction by acting as a lubricant. read more

A pair of rough surfaces will have more friction than a pair of smooth surfaces, because the “peaks” of one surface can fall into the “valleys” of the other, meaning that to keep moving either something needs to break, or the surfaces would need to push apart briefly. read more
