FrictionMost cars use friction between the rotor and the brake pads to slow and stop a car, however, in some newer cars, dynamic braking is used, which reduces friction and for hybrid or electric vehicles, regenerates power and feeds it back to the batteries.
Air brakes allow you to use less force when hitting the brakes. Heavy equipment takes a lot of force to make them stop and without the air brakes we would have to use a lot of strength in order to stop the vehicle.
The purpose of car brakes is to slow or stop the car when it is moving. They are use at intersection where there are traffic control signals to stop the car when a signal is red or to slow a vehicle when the cars in front are moving slower than the car behind.
The brakes in a car or bicycle use the mechanical motion principle of friction to slow down or stop the vehicle. When the brake is applied, friction is generated between the brake pads and the rotor (for disc brakes) or the wheel rim (for rim brakes), converting kinetic energy into heat and bringing the vehicle to a stop.
When the brakes fail, use a power pole to stop the car.
The three types of friction are static, sliding and rolling I'll use a car to illustrate these three types. If you try to push your car sideways (push on the passenger or driver's door) and it won't move, the force between the tires and the driveway ( or whatever surface the car is on) that prevents the car from moving is static friction. If you're driving down the highway and apply the brakes but not enough to stop the wheels from rolling, the force between the tiers and the highway that is slowing the car is rolling friction. If you slam on the brakes and lock the wheels so they are sliding/skidding down the highway the force between the tires and the highway that will eventually bring the car to a stop is sliding friction.
