Answer: Rougher Surfaces
Explanation: Rougher surfaces have more friction between them than smoother surfaces. The rougher surface of the soles of the shoes causes more friction and slows you down.
Answer: Rougher surfaces have more friction between them than smoother surfaces. That’s why we put sand on icy sidewalks and roads. You can’t slide as far across ice with shoes as you can on the blades of skates (see Figure below). The rougher surface of the soles of the shoes causes more friction and slows you down.
Explanation:
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force.
