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. After working on this lesson, students should be able to: identify the factors that affect the stability of racing cars; use the Bernoulli Effect to explain the difference between a moving airplane and a racing car; and use Newton's Third Law to explain the motion. As a prerequisite to this lesson, math and physics at the level of grade 10 should be sufficient. Materials needed include: blank sheets of paper; soda straws; cardboard boxes; protractors; and wooden blocks. Including the in-class activities, this video lesson will take less than an hour to complete.

Professor Ziq received his Ph.D. from the University of Illinois at Chicago in1989. His research interest is discovering new superconducting materials. He also enjoys teaching physics and often designs his own class demonstrations that simplify complex physics concepts for students. Read more about Professor Ziq here.
