When you pedal really fast on a bike, you can feel the wind slowing you down. Which force causes this?
Understand the Problem
The question describes a scenario where a cyclist feels resistance due to wind when pedaling fast and asks to identify the force responsible for this resistance. This relates to understanding the forces acting on moving objects, particularly in the context of air resistance.
Answer
Air resistance slows you down when pedaling fast.
The force that slows you down when you pedal fast on a bike is air resistance, which is a type of friction.
Answer for screen readers
The force that slows you down when you pedal fast on a bike is air resistance, which is a type of friction.
More Information
Air resistance increases exponentially with speed. The faster you go, the greater the air resistance.
Tips
Some people may think it is wind, however, the feeling of wind is caused by air resistance.
