WebCLASS 6: FRICTION. FORCE OF FRICTION Let’s start with rubbing our hands together. Does it feel warm? Why do you think this happens? Would it be easier if your hands were oily? Friction is a force that opposes the relative motion between two surfaces of objects in contact. The force of friction always acts in a direction opposite to that of the applied force. WebWet marble floor, dry marble floor, towel, newspaper. Sol: a.Wet marble floor, dry marble floor, newspaper, and towel. The nature of the surfaces in contact decides the friction force between them. It will be more if the surfaces in contact are rougher. Among them, the wet marble floor is least rough therefore will experience least force.
