Using brake pads in the brake system of bicycles and automobiles is for what pupose?

Correct option is A

The correct answer is (a) To increase friction.
· Brake pads are an essential part of the braking system in both bicycles and automobiles.
· They work by creating friction against a rotating surface (like the wheel or brake disc) to slow down or stop the vehicle.
· When the brake is applied, the pads press against the wheels, generating friction that converts the kinetic energy of the moving vehicle into heat, thereby slowing it down and eventually stopping it.
· The increase in friction is crucial for effectively controlling the vehicle's speed and ensuring safety.
· High-quality brake pads improve braking performance and reduce stopping distances, making them essential for safety.
