This web page contains an introductory physics homework assignment relating to the motion of a cyclist riding a 12-speed bicycle, developed as an alternative to traditional textbook homework. Students use observational skills and mathematical modeling, combined with basic physics, to solve problems related to the use of a racing bicycle. The problem integrates concepts of torque, friction, force, and acceleration. This item is part of a larger collection of alternative homework assignments designed for introductory physics students. Each assignment poses a series of questions about a single context. To successfully complete assignments, students must think critically about how the physical situation is represented by mathematics.
