Hello, We are doing a lab studying terminal velocity. Unfortunately we do not have a motion sensor, so we are dropping coffee filters at a certain height (both scrunched and flat- while increasing their numbers), and noting their final speeds. The thing I don't quite understand is whether and how the final speed is the terminal speed Can anyone advise? I believe it is so because this is what we've been measuring throughout our experiements. But other than that- I thought terminal velocity was that when both frictional force and gravity are equal. Thank you!
