The dataset includes results from tests of U-folded falling chain in two groups: (i) videos and (ii) tip's coordinates timeseries. In test T2 the opening of the two tips of the chain at the initial state is 0.045m, in T4 is 0.087m and in T5 is 0.128m. The length of the chain is 1.512m, while its total mass is 31g. The txt files contain three columns: time (sec), coordinate x (pixels) and coordinate y (pixels). The scale factor between distance in millimeters and pixel is 1. 576482830 mm/pixel.
