Physics: Dics Brakes and Work done by Friction

In the following video we see the kinetic energy of a rotating tire (or moving car) converted into heat. As the brake is applied, the friction in the systems does work to slow the wheel down. The energy from the work done by friction manifest itself as heat. The disc brake become hot enough to glow brightly. Here are some sample videos.
