Does sand paper reduce or increase friction
WebFriction is the resistance of motion when one object rubs against another. Anytime two objects rub against each other, they cause friction. Friction works against the motion and acts in the opposite direction. In some cases we want to prevent friction so it's easier to move. A good example of this is a ball or wheel. They roll to help reduce ... WebSep 28, 2011 · sand paper increases friction, that is to say that it is harder to slide something on sand paper than it is on a smooth surface.
