Veronica observes how the force of friction causes an object to slow down. She writes the following observation: When an object moves across a smooth surface, there is less friction created than when an object moves across a rough surface. When the object stops moving, friction is created. Which statement corrects the error(s) in Veronica's observations? It is not smooth or rough surfaces that affects friction. It is the size of the push.
When an object moves across a rough surface, there is no friction.
When an object moves across a smooth surface, the friction increases.
When an object stops moving, there is no friction.
