The techniques combine the use of long exposure photographs and frameby-frame video analysis. In one of the experiences the transition from rolling to sliding is made evident, while the other examines the effect of slipping on the mechanical energy %K long exposure photography %K rigid body %K rolling. %U http://www.lajpe.org/mar12/24_LAJPE_614_Eduardo_Rodriguez_preprint_corr_f.pdf
