I have a lab for physics that I have to demonstrate the smallest possible force. The force has to be mearsured by multiplying the mass of the designated object by acceleration. It has to have a continuous and positive acceleration. The distance is that it must travel at least 30 cm. Any ideas and help would be great :). I had an idea using the air track with a paper clip but it would be kinda typical for our class since everyone is doing it since no one knows what to do. Thanks.
