Question
A bicycle stops when its brakes are applied. This is because its ____ rub against the ____ to give rise to friction.
- Brakes, ground
- Brake pads, rim
- Brake pads, tyres
- Brakes, rim
The correct answer is: Brake pads, rim
A moving bicycle slows down and stops quickly when its brakes are applied. When the hand brakes are applied, the brake pads near the tyres rub against the rim. This gives rise to friction, which slows down the motion of the tyres and eventually stops it.
