Final answer:
Friction affects ice skating, sandpaper, and bicycling differently.
Step-by-step explanation:
Friction affects different objects in different ways. In the case of ice skating, the friction between the ice and the skates is reduced through the use of a lubricant, resulting in low friction. Sandpaper, on the other hand, is designed to have a high friction surface, which allows it to rub against other objects and remove material. Bicycling involves the interaction between the tires and the ground, where friction is important for maintaining traction and allowing the wheels to grip the surface.
