A student investigates how air resistance affects falling objects using basket-shaped paper coffee filters.
One coffee filter is shown in Figure 1.
The student drops a stack of these coffee filters with the flat base facing downwards, as shown in Figure 2.
The terminal speed of the falling stack depends on the mass of the stack, which is varied by nesting different numbers of filters together.
The student has a stack of coffee filters, a stop clock, and a metre rule.
Describe an investigation to show how the terminal speed of the falling stack depends on the number of coffee filters in the stack.
