Students investigate rotational equilibrium, discover ways to locate an object’s center of mass, and develop integration skills by practicing on useful problems. Some overlap between this unit and the adjacent ones is beneficial. The timing of lab exercises can be adjusted to fit lab schedule. Problems from old A.P. examinations make excellent homework assignments. Students must learn to write out solutions clearly enough so that any classmate can understand their reasoning when papers have been exchanged.
Topics include Inventing Torque, Center Of Mass, More About Center of Mass (experiment), The Roberval Balance (experiment), The Center Of Mass of a Wire Arc (experiment), Wire Arc Pendulum Project (experiment).
