Brake pads in a bicycle stop the wheel by:
ARemoving air around the wheel
BIncreasing the force of friction between the pads and the rim
CReducing the friction between the wheel and the road
DPulling the wheel magnetically
Answer & Solution
Correct answer: B. Increasing the force of friction between the pads and the rim
When the brake lever is pressed, the brake pads press against the rim. Friction between the pads and the rim slows down (and eventually stops) the wheel. Brakes work by deliberately increasing friction.
