This interesting activity examines the effect ofweight upon terminal velocity. Gather together some nested coffeefilters. Leaving them in their original shape, measure the time ittakes for one, two, three, four, and five nested filters to fall tothe floor from the same height (roughly 2 m). (Note that, due tothe way the filters are nested, drag is constant and only massvaries.) They obtain terminal velocity quite quickly, so find thisvelocity as a function of mass. Plot the terminalvelocity, v versus mass. Also plot v-squared versus mass. Which of these relationships is morelinear? What can you conclude from these graphs?
