Then there is a change in the position of the rope. Think about a ball rolling on the floor. Over time, it slows down. A force must be acting on the ball. The force that slows down the ball is friction.
Friction is a force that occurs when one object rubs against another.
The ball rubbing on the floor creates friction. Different materials produce different amounts of friction. Rough materials rub best. They produce a lot of friction. Most smooth materials do not rub well.
