We study the ascending motion of a disk rolling on an incline when its centerof mass lies outside the disk axis. The problem is suitable as laboratoryproject for a first course in mechanics at the undergraduate level and goesbeyond typical textbook problems about bi-dimensional rigid body motions. Wedevelop a theoretical model for the disk motion based on mechanical energyconservation and compare its predictions with experimental data obtained bydigital video recording. Using readily available resources, a very satisfactoryagreement is obtained between the model and the experimental observations.These results complement previous ones that have been reported in theliterature for similar systems.
