Question

Give two reasons why it is useful for the cyclist to reduce friction​

Answer 1

Answer:

• In order to move forward, the cyclist must push through the mass of air in front of her. This takes energy. Direct friction occurs when wind comes into contact with the outer surface of the rider and the bicycle. Racing cyclists often wear "skinsuits" in order to reduce direct friction.
• Reducing friction (or grip in layman's terms) would cause your wheel to simply spin in circles when you pedal and you would fall down. Increased friction between the tire and the riding surface is the goal of nearly every tire manufacturer.

Hope it helps :)
