Answer» tion is a force between two surfaces that are SLIDING, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult.Friction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down.The amount of friction DEPENDS on the materials from which the two surfaces are made. The rougher the surface, the more friction is produced. Friction ALSO produces heat. If you rub your HANDS together quickly, you will feel them get warmer. |
