What I learned about Elastic Force in Rubber Bands rises

           Elastic Force is measured in newtons. You connect a rubber band to a newton scale and hook the othe end of the band to something thatt wont move. You pull thee newton scale which will stretch the rubber band and then it will tell you how much elastic force its using in newtons at the certain points where you stop pulling the band. When you use a more strechy rubber band the less elastic force it will take to pull it 20.cm then if you used a unstretchy rubber band.
