How many ways does friction help your vehicle to stop?

Friction plays a crucial role in helping a vehicle to stop, and there are typically two primary ways it accomplishes this task. First, friction between the tires and the road surface allows the vehicle to decelerate when the brakes are applied. The brakes create friction against the wheel, which in turn affects the tires' grip on the road, enabling the vehicle to stop effectively.

Second, friction is also involved in the braking system itself, where brake pads must create sufficient friction against the brake rotors. This mechanical interaction converts kinetic energy into thermal energy, slowing down the vehicle as a result.

Both of these frictional interactions are essential for effective braking and vehicle control, which is why the correct answer is that there are two main ways friction helps your vehicle stop.
