Nov 24, 2016 · To study the conservation of energy of a ball rolling down on an inclined plane (using a double inclined plane). Apparatus A double inclined plane (track), a steel ball of diameter about 20 cm, two wooden blocks (2.5 cm length), two weights of one kg each. Stop clock/watch, plumb line, metre scale, spirit level. Theory Figure 1 shows an example of an approximately planar retrogressive wavefront, generated by a straight perturbation across the full width of the inclined plane (figure 2). The retrogressive wave separates a thicker upslope layer of static grains from a thinner downstream layer of flowing grains.
