Generally speaking for cars that have "disk brakes", friction slows the car. When the driver presses down on the brake pedal the brake calipers squeeze the brake pads against the brake rotor inside each car wheel causing the car to slow down by friction.

What slows the car?

Applying the brakes.


What force allows a car's brakes to stop a car?

Friction between the brake pads and the rotors creates a force that slows down the car's wheels, ultimately stopping the car. This friction converts the kinetic energy of the car into heat energy, dissipating it into the environment.


What force causes a car to stop?

The force of friction between the tires and the road surface is what primarily causes a car to stop. When the brakes are applied, the brake pads press against the rotating wheels, generating friction that slows down the car.

If only external force can change the velocity of a body how can the internal force of the brakes bring a car to rest?

It is not the force of the brakes that is stopping the car but rather external force of friction between tires and the road. Notice that no matter what the force at the brakes is, the car won't stop if there is no friction there(ie. the road is slippery). This is an excellent question. Consider the NASA space shuttle. It has brakes, yet the brakes work only on the ground - only while the shuttle is landing. Why? In space, the brakes have nothing to react against. So, as the questioner suspects, the internal forces of the brakes alone are not sufficient to change the velocity of the space shuttle. But once the shuttle lands, and is rolling down the runway, applying the brakes creates friction between the wheels and the runway. And it is the external force of the runway pushing back against the braking wheels that causes the shuttle to slow down.


How does the use of car brakes reduce friction?

When car brakes are applied, they create friction between the brake pads and the wheels. This friction slows down the wheels, reducing the car's speed.


When a car stops the brakes heat up because of friction what is this an example of?

This is an example of kinetic friction, which is the force that opposes the motion of two surfaces sliding against each other. When you apply the brakes in a car, the brake pads exert a force on the rotating wheels, resulting in friction that slows down the car and generates heat due to the surfaces rubbing against each other.


Why does the brakes get hot when a car slows down?

Friction causes the heat.
