Have table of results made from the experiment, where two balls are colliding. Three types of balls were taken for the experiment-squash balls, golf balls and steel balls. The mechanism of colliding was similar to Newton’s cradle. Each ball was dropped from heights ranged 20-75 and afterwards with the help of the video was 2 height collected. The data is included in files and the marscheme as well which should be followed. Graphs should be done as well as calculations, simple ones.
