National Science Foundation
National Science Foundation: Science of Speed: Grip
Success in auto racing depends on the grip of a car's tires. Grip is the frictional force that holds the tires on the track. Aerodynamic features of a car also improve a car's grip. [5:02]

National Science Foundation: Science of Speed: Friction and Heat
Friction always creates heat. Brakes and tires depend on friction to work, while the opposite is true of an engine. Engine builders use oil and high-tech coatings to get more power from an engine. [5:25]
