"A principle of physics that states that the force needed to stretch or compress a spring by a distance is proportional to the distance. Did you get to do the lab for that by the way? It was a pain using those weights because they were so worn some of them don't weigh what they are labled as. Then using the scale got annoying because there were only two since the Physics club had taken them to use and hadn't returned them yet."
