When the driver brakes an automobile, it is because he or she wants to slow down and bring the car to a stop. braking is different from accelerating which, instead reverses and decelerates rotation of the flywheel. when braking, friction (internal forces) work against the frictional forces that oppose movement; this works as either kinetic friction (if not enough energy is provided) or static friction (once moving). wear on brake pads slows the wheel's spinning rotation.
braking induces wear on brake pads and produces heat that transfers into various parts of a vehicle's body – often creating undesired paint damage through rusting or scorching. some drivers have been known to use their cars' air-conditioning
