This 20-minute video segment highlights the forces at work on a racecar as it travels around a track. It was designed to promote understanding of velocity as a vector quantity with both magnitude and direction. It also offers an engaging view of factors to be considered in the design of a racecar: torque, drag reduction, and frictional force that is necessary to achieve fast (but safe) cornering. Background information and discussion questions are also provided.
Teachers' Domain is an NSF-funded pathway of the National Science Digital Library (NSDL). It is a growing collection of more than 1,000 free educational resources compiled by researchers and experienced teachers to promote the use of digital resources in the classroom.
