This video lesson discusses how a few simple physics concepts can help in understanding various factors that influence the performance of racing cars. Students will also learn how these same concepts influence the design and development of a racing car that is safe and able to compete in various racing conditions. In particular, this lesson examines what goes on outside the car: the aerodynamics of air flowing above the body of the car and how friction and Newton’s third law affects the motion and the interaction between the tires and the road.
