Friction - Simple English Wikipedia, the free encyclopedia

WebbPut simply, friction is the force that two surfaces exert on each other as they rub against each other. In terms of sledding, friction occurs as the sled moves across the snow, thus causing resistance. The rougher a surface is, the more resistance or friction occurs. For example, imagine trying to ski down a grassy hill that has no snow.
